Per https://dba.stackexchange.com/questions/182840/repacking-rds-database-with-pg-repack-isnt-online (and personal experience), pg_repack on tables will cause issues because RDS uses a pseudo super user instead of the normal superuser that is expected.
The documentation should be updated to include the required permission changes
The web page is available at
https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.IAMDBAuth.Connecting.AWSCLI.PostgreSQL.html
It also has a small error:
export PGPASSWORD="$(aws rds generated-db-auth-token --hostname $RDSHOST --port 3306 --region us-west-2 --username jane_doe )"
it should be aws rds generate-db-auth-token …
i see below error when i update the code. can anyone help on same ?
Hi
I was checking the documentation, and making a RDS migration from VPC. It now says
DB instance status: moving-to-vpc
There is no status information on this section of DB instance status: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Overview.DBInstance.Status.html
There is a good description of the process here: https://aws.amazon.com/premiumsupport/knowledge-center/change-vpc-rds-db-instance/
Also, I think that there is a restriction of the number of movements in parallel but I got no information about this.
Quote from the doc
"The string can contain only the set of Unicode letters, digits, white-space, '', '.', '/', '=', '+', '-' (Java regex: "^([\p{L}\p{Z}\p{N}.:/=+\-]*)$")."
But if you look at the regex it seems ':' is also allowed so statement should probably look like
Do note addition of ':'
"The string can contain only the set of Unicode letters, digits, white-space, '', '.', ':', '/', '=', '+', '-' (Java regex: "^([\p{L}\p{Z}\p{N}.:/=+\-]*)$")."
I'm currently running into an issue with pg_tranport that only outputs the following message: ERROR: failed to download file data
SQL state: XX000
There is no documentation on errors that are outputted from the function, and given the closed source nature of the function, there is simply no way to understand what might be missing.
I am trying to export the cloudwatch logs from my aurora postgres instance running version 9.6.8, but I am getting the following when running the command:
$ aws rds modify-db-cluster --db-cluster-identifier <db-cluster-id> --cloudwatch-logs-export-configuration '{"EnableLogTypes":["postgresql", "upgrade"]}'
An error occurred (InvalidParameterCombination) when calling the ModifyDBCluster operation: Engine aurora-postgresql 9.6.8 does not support exporting to CloudWatch Logs. For supported engine versions, see the documentation.
The documentation states in https://github.com/awsdocs/amazon-rds-user-guide/blob/master/doc_source/USER_LogAccess.Concepts.PostgreSQL.md that "Publishing log files to CloudWatch Logs is only supported for PostgreSQL versions 9.6.6 and above and 10.4 and above."

Folks may not remember how overwhelming it is to get started with AWS. In hindsight, after a couple of Google searches for the error you do eventually find a solution.
When creating the RDS instance you are prompted for a database name. This name turns out to be the instance name, not the database name. When using the commands for psql you will get an error along the lines of "the database name does not exist", which is in fact, true.
A database is created by default when there is no additional configuration and its name is postgres. I had this issue and using postgres as dbname solved my problem.
I created this PR to solve this issue: #61
https://github.com/awsdocs/amazon-rds-user-guide/blob/master/doc_source/SQLServer.Procedural.Importing.md has bad information relating to the IAM role for encryption.
IAM kms:GenerateDataKey can not have specific resources according to IAM. This results in a warning and a missing permission.

Under Compressing Backup files the docs state:
exec rdsadmin..rds_set_configuration 'S3 backup compression', 'true';
and exec rdsadmin..rds_set_configuration 'S3 backup compression', 'false';
These commands fail with Msg 50000, Level 15, State 1, Procedure rds_set_configuration, Line 34
Unrecognized configuration name provided: S3 backup compression
Correct commands appear to be:
exec rdsadmin..rds_set_configuration 'S3 Backup Compression', 'true'; and
exec rdsadmin..rds_set_configuration 'S3 Backup Compression', 'false';
Note case sensitivity.
Hi there,
I am wondering if this issue is still present in MySQL 5.7.21?
The bug that is referenced (https://bugs.mysql.com/bug.php?id=79379) says "Version: 5.7.9". But I am not able to find the bug referenced in any 5.7 changelog items.
Thanks!
I can add an additional read-only endpoint to my RDS Proxy
So I guess we can rewrite this
For an Aurora DB cluster, all proxy connections have read/write capability and use the writer instance. If you use the reader endpoint for read-only connections, you continue using the reader endpoint the same way.
As we could actually use RDS proxy to pool connections to RDS read slaves? (That's my understanding)
Short:
I expect to see the "Add all the subnets related to this VPC" option when making an DB Subnet, but instead all I see is a dropdown of all of my subnets which I must individually select.
Longer:
In the "Create a DB Subnet Group" guide's Step 5 it says:
In the Add subnets section, choose Add all the subnets related to this VPC.
Yet I did not see this option in the dropdown.
See the photo below where my 3 subnet IDs have been anonymized.
I believe the smallest instance type supported is now db.t2.micro
https://docs.aws.amazon.com/IAM/latest/UserGuide/list_amazonrds.html references the DownloadCompleteDBLogFile API action which links to here https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/RESTReference.html#RESTReference.DownloadCompleteDBLogFile
This link is broken and redirects to the home page of the RDS User Guide: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Welcome.html
This API does not exist int he API documentation (control, data, and insights) so I suspect it's been deprecated and should be removed from the table. Is this correct?
Control API actions: https://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_Operations.html
If you try to migrate a snapshot or existing RDS MySQL database to Aurora that has options set that Aurora doesn't support (my example is Memcached, there may be others), it will fail and result in a broken cluster. Support didn't point me in the right direction, they assumed the snapshot was corrupted, but removing the offending options solves it.
Is this worth noting somewhere as it would have saved me a few hours of pain and back and forths with support?
(OR did it just miss it somewhere?)

This is all I could find.
I was looking for a way to query a very basic RDS Instance property, its instance name, and couldn't even find a way to do that after 2 days of googling.

using workbench to connect with RDS server and mysql server
I’m getting this error: you don’t have admin privileges to import the DB while I already have the super admin access because I’m using the superuser I created while creating the RDS MySQL database. This error doesn’t arise all the time but sometimes. Still, I didn’t get any proper solution to get this issue resolved. I don’t know why it gives super admin privileges here and I think a solution should be provided here at the end of the doc because other users are also facing this problem. After all, I had seen other members also on stack overflow.
I work with RDS a good amount, but I work with lots of other AWS and non-AWS services and tools. Every time I come back to Option groups and/or Parameter groups, I always forget what the distinction is between the two and I end up here https://www.reddit.com/r/aws/comments/5r0l8e/what_is_the_difference_between_rds_option_groups/.
I would be helpful if you had another page here https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_RDS_Configuring.html, something short, literally titled Option groups vs Parameter groups. I suspect that I'm not alone. I am certain that users who are new to RDS will benefit from this.
In the Common DBA Tasks for PostgreSQL appendix, the pgBadger snippet no longer works for pgBadger version 10.x when used against Amazon RDS for PostgreSQL logs that worked previously:
$ pgbadger --version
pgBadger version 10.1
$ pgbadger -p '%t:%r:%u@%d:[%p]:' postgresql.log.2018-10-05-15
FATAL: unable to detect log file format from postgresql.log.2018-10-05-15, please use -f option.According to darold/pgbadger#443, this is because pgBadger can no longer automatically detect the log format. The following snippet appears to work consistently:
$ pgbadger --version
pgBadger version 10.1
$ pgbadger -f stderr -p '%t:%r:%u@%d:[%p]:' postgresql.log.2018-10-05-15

In Step 4 of "To configure IAM permissions for using your cluster with Lambda" Documentation code says:
aws rds add-role-to-db-cluster \
--db-cluster-identifier my-cluster-name \
--feature-name Lambda \
--role-arn arn:aws:iam::444455556666:role/rds-lambda-role \
--region aws-region
I do not know where to find the db-cluster-identifier and I do not think I have one. Also when I look at AWS CLI documentation in the link you provided:
https://awscli.amazonaws.com/v2/documentation/api/latest/reference/rds/add-role-to-db-cluster.html
It states:
add-role-to-db-cluster
--db-cluster-identifier <value>
--role-arn <value>
[--feature-name <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
And I am guessing db-cluster-identifier is the DB instance ID under the configuration tab in the AWS RDS console? Is that correct?
I can't find the table in the source file but this page contains a table of endpoints:
https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concepts.RegionsAndAvailabilityZones.html

Hello, I noticed that the default for RDS mysql 5.7 and 8 parameter groups SQL_MODE option is different from the MySql default.
The default on MySql 5.7 is specified here: https://dev.mysql.com/doc/refman/5.7/en/faqs-sql-modes.html#faq-mysql-what-default-mode
The default for mysql 8 is specified here: https://dev.mysql.com/doc/refman/8.0/en/faqs-sql-modes.html#:~:text=The%20default%20SQL%20mode%20in,%2C%20%E2%80%9CServer%20SQL%20Modes%E2%80%9D.
Whereas the RDS default seems to be NO_ENGINE_SUBSTITUTION for both versions.
I understand how to change it, but I wondered if it was possible to document why the default is different, whether there are any benefits to the different default and why AWS recommends this default?
The reason for asking is that we noticed a difference between our local environments and AWS RDS and we're unsure on whether we should deliberately override the AWS recommendation. All the documentation I can find is about changing it, not why it's set like this.
This statement from the Doc, seems to be misleading
"You can create an encrypted Read Replica of an unencrypted DB instance, and you can create an unencrypted Read Replica of an encrypted DB instance. "
Tried to reproduce this with Aurora, the encryption option is available and when you select it, it ends up not creating an encrypted instance from the unencrypted aurora instance.
This is made clear here --> https://aws.amazon.com/rds/aurora/faqs/
Q: Can I encrypt an existing unencrypted database?
Currently, encrypting an existing unencrypted Aurora instance is not supported. To use Amazon Aurora encryption for an existing unencrypted database, create a new DB Instance with encryption enabled and migrate your data into it.
Hi,
In https://github.com/awsdocs/amazon-rds-user-guide/blob/master/doc_source/UsingWithRDS.IAMDBAuth.IAMPolicy.md you suggest to use a different ARN format to specify the resource an IAM user can connect to:
arn:aws:rds-db:region:account-id:dbuser:dbi-resource-id/database-user-name
vs the usual RDS form:
arn:aws:rds:us-east-2:123456789012:db:my-mysql-instance-1/database-user-name
Notce rds vs rds-db and dbuser vs db.
It seems like using the later RDS format works too, but it's not explicit in the doc.
Are both supposed to work? Or is it just an edge case that was forgotten and is not supposed to work?
Once I know, I can PR the doc to make it more explicit if you want.
Thanks!
In this page https://github.com/awsdocs/amazon-rds-user-
guide/blob/master/doc_source/Appendix.SQLServer.CommonDBATasks.Logs.md, it says we can use the following command to read the error log:
EXEC rdsadmin.dbo.rds_read_error_log @index = 0, @type = 1;
I tried the native command EXEC sp_readerrorlog and it also works. So what's the difference and why we need to use rdsadmin.dbo.rds_read_error_log?

Document says 9.6.12 can go to any 10.x version but only allows 10.7.
I have been trying to use cli to export my aurora-postgresql logs to cloudwatch but the log types doesn't seems to be supported.
Here is the error
$ aws rds modify-db-cluster --db-cluster-identifier xxxxxxx --cloudwatch-logs-export-configuration '{"EnableLogTypes":["postgresql"," upgrade", "audit", "slowquery"]}'
An error occurred (InvalidParameterCombination) when calling the ModifyDBCluster operation: You cannot use the log types ' upgrade', 'audit', 'slowquery' with engine version aurora-postgresql 9.6.12. For supported log types, see the documentation.
I've also tried with aurora-postgres version 10.7 and got the same error.
Please let me know what log types are supported by this feature for the two versions of aurora as I cannot find it in any of the AWS documentation.
I have also done extensive reading of this documentation:
https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraPostgreSQL.CloudWatch.html
The cluster-level DB parameter server_audit_logs_upload parameter mentioned in the documentation above doesn't seems to be a valid parameter as I could not find it in my cluster parameter group. Is there something i'm missing or you need to update to your documentation to reflect how it actually works?
I have enabled read replication(in 2 different AZs) for my RDS instance running mysql v5.7.19. I am trying to get the details about the events that are taking place in the instance. For this, I want the bin logs from the instance.

This page states that you cannot remove encryption from an RDS instance: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Overview.Encryption.html#Overview.Encryption.Limitations
That's fine but you could also mention workarounds for this. I believe that you can accomplish this by using a tool like DMS, a home grown script or a connector from a third party vendor.
While generally, you wouldn't want to remove encryption, it's the kind of thing you might need to do in an emergency.
It's frustrating when the AWS doc leads to dead ends like this with a "Oh well, you're screwed if you're stuck in this situation".
com.amazonaws.services.rdsdata.model.AWSRDSDataException: Rate exceeded (Service: AWSRDSData; Status Code: 400; Error Code: ThrottlingException;I can't find the above error content for API Limit in the document.
Sadly there's no way to send a pull request for the content on https://aws.amazon.com/rds/instance-types/ and the support is only about billing or technical stuff. I found no better way than to report it here.
In section Memory Optimized, tab X1, the models in the tables are missing the db. prefix (x1.16xlarge vs db.x1.16xlarge).
This is relevant, because it makes it harder to scrape the page and use the result to check eg. https://github.com/cloudtools/troposphere/blob/dbf1ab10b02e0efc3c55548c9dee3782af801c9e/troposphere/constants.py#L332-L410 for completeness.

The Working with PostGIS guide is a little misleading. It's not setting up only the postgis extension, but also the extras fuzzystrmatch, postgis_tiger_geocoder, and postgis_topology.
Loading these extras is unnecessary for applications that only use basic PostGIS functionality. This includes the popular Django GIS extension which is what I am looking at setting up.
I suggest it be split into two guides: PostGIS (basically only CREATE EXTENSION IF NOT EXISTS postgis, and the PostGIS extras.
You can also use Provisioned IOPS SSD storage with read replicas for MySQL, MariaDB or PostgreSQL. The type of storage for a read replica is independent of that on the master DB instance. For example, you might use General Purpose SSD for read replicas ith a master DB instance that uses Provisioned IOPS SSD storage to reduce costs. However, your read replica's performance in this case might differ from that of a configuration where both the master DB instance and the read replicas use Provisioned IOPS SSD storage.
For example, you might use General Purpose SSD for read replicas ith a master DB instance that uses Provisioned IOPS SSD storage to reduce costs.
'ith' should be 'with'. it's a little typo.
I am working on consolidation of AWS RDS postgres db instances. There are around 40 individual postgres RDS db instances. These 40 instances are not utilized fully. CPU Utilization is below 5% for all. So planning to migrate / consolidate these 40 instances into few instances like around 4. I am thinking of two options. 1. Use pg_dump and 2. Use pg_transport. I would like to know what is the best option for this. I haven't used pg_transport. Any suggestions highly appreciated. I am little new to AWS RDS postgres db instances.

when we entered above code this cluster module is not available and if we entered aws rds help so in that to this create-db-cluster module is not available thn why they why it is available in aws official documentation.
