Re: Postgres log(pg_logs) have lots of message

That’s just that some other process has some DML going on in the table that is supposed to be truncated.  No lock, no truncate.

HTH,

Hi,

 

Could some please explain what these warnings mean in postgres.

I see these messages a lot when automatic vacuum runs.

 

      1 tm:2013-04-10 11:39:20.074 UTC db: pid:13766 LOG:  automatic vacuum of table "DB1.nic.pvxt": could not (re)acquire exclusive lock for truncate scan

      1 tm:2013-04-10 11:40:22.849 UTC db: pid:14286 LOG:  automatic vacuum of table "DB1.nic.pvxt": could not (re)acquire exclusive lock for truncate scan

Thank you

Nik
