I need to ask about last_autovacuum column in pg_stat_all_tables.
I'm not sure is this a starting time, or when the daemon finished.
I make an "accident" with changing many rows in a huge table.
I didn't want to start autovacuum with this operation.
They reported slowing, but I'm not sure this caused the problem or other thing.
This points to night, but I don't know is this the starting of the cleaning, or when the daemon finished, so how to calculate the daemon's working interval.
Thank you for your help!
Best regards
dd
last_autovacuum
timestamp with time zone
Last time at which this table was vacuumed by the autovacuum daemon
