We are using postgres 9.2 version on Centos operating system. We have around 1300+ tables.
We have following auto vacuum settings are enables. Still few of the tables which are always busy are not vacuumed. Due to that tables are bloating and observed few areas has performance degradation.
autovacuum_max_workers = 6
autovacuum_naptime = 15s
autovacuum_vacuum_threshold = 25
autovacuum_analyze_threshold = 10
autovacuum_vacuum_scale_factor = 0.1
autovacuum_analyze_scale_factor = 0.05
autovacuum_vacuum_cost_delay = 10ms
autovacuum_vacuum_cost_limit = 1000
To avoid the above problem, I am planning to make '
autovacuum_vacuum_scale_factor' value to zero and
autovacuum_vacuum_threshold value to 150. Please suggest me does it have any negative impact.
