Asunto: pgstat wait timeout
In my postgres log I saw a lot of warning like this…
WARNING: pgstat wait timeout
Every 10 seconds aprox since yesterday and after one year working without any warning
I have postgres 9.0.3 on a Windows Server 2008 R2.
I have only one big table with aprox. 1,300,000,000 (yes 1,300 millions) rows the table is not used just keep historical record, could be this the reason, some autovacuum over this table?
pg_stat_activity not show any autovacuum over this table but yes over the transactional table, right now the autovacuum about transactional table is taking 30 minutes (now() - xact_start )
Thanks
