Hi,
I have the following configurations.
On master:
autovacuum=off
vacuum_defer_cleanup_age=0
On slave:
hot_standby_feedback = off
max_standby_streaming_delay = 30s
Now when I try to run a long query on slave and do some update or delete on
the table on master I am getting the following error.
ERROR: canceling statement due to conflict with recovery
DETAIL: User query might have needed to see row versions that must be
removed.
The error code was : 40001
I am not running vacuum manually and autovacuum is 'off'
What could possibly causing the conflict?
