I am running a PG10.4 in a RHEL 6.9. 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,
