Error collecting replication statistics about collector

[lfittl]

@declaresub Thanks for the report - did you create the monitoring user functions, in particular this one, as a super user:

CREATE OR REPLACE FUNCTION pganalyze.get_stat_replication() RETURNS SETOF pg_stat_replication AS
$$
  /* pganalyze-collector */ SELECT * FROM pg_catalog.pg_stat_replication;
$$ LANGUAGE sql VOLATILE SECURITY DEFINER;

[declaresub]

Yes; that function exists in my pganalyze schema.

[declaresub]

In my db, SELECT * FROM pg_catalog.pg_stat_replication returns a single row, with the value of replay_lsn being NULL. I expect that's the offending column.

@declaresub Which collector version are you using?

It seems that this is the bug that got fixed about a year ago in 1fa72e2 (which first got released in v0.9.13)

[declaresub]

I'm using 0.12.0.

[lfittl]

@declaresub My apologies, this was actually a bug - this is now fixed in the newly released 0.13.1 collector version.

Let me know in case that doesn't fix the issue you were seeing!

@lfittl I'm seeing this in the current stable, which AFAICT is v0.17.1

If it's any help, I see this on RDS masters and not on replicas.

@dexterous Thanks for your note, and sorry for the late reply.

Based on the report in #34 this is now more flexible and should not error out anymore. We'll have a new release soon that includes this bugfix.
