I have joined 2 days back and I have tried educating them for enabling the same but they said after enough testing and evidence collected it will be enabled back in future.. As of now, I have started the manual vacuum operation on the databases but in one of them I am facing this issue that my vacuum jobs for 3 tables are paused as there are 3 autovacuum jobs running since 5 days on the same tables to prevent wraparound. Could you please confirm whether I can stop these autovacuum jobs so that I can run my manual run of vaccum job. Thanks, Rijo Roy

The tables stored in my database are mainly used for reads and very less writes happen. I have recently joined this environment and as soon as I logged into the postgresql servers, checked for dead tuples and relfrozenids.. And almost all have reached the autovacuum_freeze_max_age of 2billion and autovacuum was disabled.. Last vacuum was run 3 months back. Today I got permission to vacuum the tables but for 3 tables, Postgresql has already started the vacuum freeze using the autovacuum daemon running to prevent wraparound and these tables have TB'S of data.Experts, please confirm whether I can kill these sessions and run a manual vacuum job with parallel jobs. Thanks in advance. Regards, Rijo Roy Sent from Yahoo Mail on Android
