Subject: RE: Extremely slow autovacuum:vacuum to prevent wraparound
Hi Steve,
Apologies, I misread it as 2 billion, it is as you said set as 200 million
which is the default value for the parameter autovacuum_freeze_max_age.
I just wanted to confirm whether there would be any impact if I cancel or
terminate the backend for the existing autovacuum :vacuum table_name (to
prevent wraparound). I have initiated a normal vacuum manually but it is stuck
on the table where the autovacuum is processing it.
Thanks,
Rijo Roy
Stack Overflow confirms my memories about killing autovacuum -
pg_cancel_backend() should be fine.
