*Hello*, We are working on a payments systems which uses postgreSql 9.6 as backend DB and blockchain technology. The database is setup in HA in master-standby mode using pacemaker on Linux 7.6.
*We are new to postgres and ne*ed help in deciding how to set value for max_connections on DB. 1. How can we decide on optimal value for max_connections for a given setup/server? I checked many posts saying that even 1000 is considered as a very high value but we are hitting the error too_many_connections due to Max_connections value limit. 2. We usee hikari pool on the client side but that even has limitations. Implementing pg_bouncer is another suggestion in the posts. In a HA setup, do we have to set it up on both primary standby? Please provide your advice/suggestions. Thanks.
