Hi Mark, When the problem appears, vacuuming is not helping. I ran vacuum manually and the problem was still there. Only full vacuum worked. As far as I have understood, autovacuuming is NOT doing FULL vacuum. So, messing around with its values should not help me in any way. Thanks > > Given that vacuum full fixes the issue I suspect you need to have autovacuum set wake up much sooner, not later. So autovacuum_naptime = 28800 or even = 60 (i.e the default) is possibly too long. We have several database here where I change this setting to 10 i.e: > > autovacuum_naptime = 10s > > > in order to avoid massive database bloat and queries that get slower and slower... > > You might want to be a bit *less* aggressive with autovacuum_vacuum_scale_factor - I usually have this at 0.1, i.e: > > autovacuum_vacuum_scale_factor = 0.1 > > > otherwise you will be vacuuming all the time - which is usually not what you want (not for all your tables anyway). > > regards > > Mark > > > -- > Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) > To make changes to your subscription: > http://www.postgresql.org/mailpref/pgsql-performance -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
