Hi,

These log lines are not an indication of a problem, but on busy / underpowered servers you might see them a lot. The way you can tell it's not an error is because of the "nowait" clause, which means "try to do this immediately, and if you can't, don't wait, just give up". When such a statement can't execute immediately, CS will retry. You can probably adjust the postgres settings to make such messages not appear if you desire.

I asked the postgres folks, and they said this isn't possible. You can turn down the logging, but there's no way to exclude only 'nowait' statements from being logged.

Hi,

I see following two lines in postgres.log.

What needs to be done so that these lines do not appear in postgres.log?
