Re: Hot Standby performance issue

Today morning I found that the performance issue on standby database was
fixed by itself. On further investigation I found that one of the biggest
used in this query had autovacuum  kicked in yesterday on primary. The last
time it had autovaccum ran was on Sep 30th.

I am suspecting that this should have been fixed the issue. The table has
update and delete operations. Only thing I did not understand why postgres
did not pick this table for autovacuum all these days, in spite of this
table is one of the busiest table from DML perspective. I was monitoring the
primary database activity all these days and always could see autovacuum was
running on another tables.

Thanks.
