Hello all,

Your expertise is needed on this. I was going through previous mails regarding the same topic and was able to setup the slave with hot_standby_feedback  enabled.
Queries are running fine with bloat occuring on master.

I tried the below scenario, where i disabled hot_standby_feedback and on table level disabled autovacuum for 2 big tables on master. Ran the query on the slave machine but still conflict error occurs.

I checked the pg_stat_database_conflicts view, the counter is increasing for confl_snapshot.  Cross-checked with pg_stat_user_tables view,  last time autovacuum happened for the 2 tables was 1 day before.


My doubt, even though no autovacuum and no DML activities happening for both the tables in master. Why is conflict error occuring?



Thanks & Regards,
Rajamohan.J
