Have you scoured the Patroni and Postgresql logs?

Have you increased the logging level?

Is there a way to narrow down the cause of failover? Yesterday itself failover happened 7 times.

Hi
First of all, read a logs.
$PGDATA/log
#journalctl -u patroni
I had once failover flapping, because of master heavy load, caused by apliccation change. So, find a pattern.

If physical replication, after failover you don't need run a vacuum manually if autovacuum is enabled.

Hi,

When I issue command patronictl history, I can see frequent failover. Like atleast weekly once.

Every time this happened we have to do vacuum analyse for all dba.

So, I need assistance in how to avoid frequent failovers and what is the solution for vacuum part we r doing..
