Vacuum delete only about amazon-redshift-utils

Thanks for spotting this. It's now fixed in eb0d435.

I am not sure how you tested this but when I do run the script that is generated like below

begin;
lock ...
...
commit;

vacuum delete only;

I am simply running each statement using a pg8000's connection.cursor() and cursor.execute(statement) i get an error like below

ProgrammingError: (u'ERROR', u'25001', u'VACUUM cannot run inside a transaction block', u'/home/rdsdb/padb/src/pg/src/backend/access/transam/xact.c', u'2541', u'PreventTransactionChain', u'', u'')

I am not sure how the utility would avoid this error.

Also is the vacuum really needed if no update/delete operations are actually performed by this script? It only seems to insert/drop tables.

[IanMeyers]

I will look into the transaction issue you are reporting and get back to you. You can safely remove the VACUUM DELETE, especially if you have VACUUM processes running at some other time.

[IanMeyers]

So yes - have clarified that this vacuum is not required. Will remove in a subsequent patch.

Great. Thanks!
