Dear all, I have question regarding how extensions acting during switchover process.
We running PostgreSQL 11 HA primary/replication server that is configured with repmgr. Everything works fine but I am interested in matter of how extensions works during failover/switchover.process. Let's say: postgresql.conf configuration file on primary server: shared_preload_libraries = 'pg_stat_statements,xxxx' *Contrib package is installed on primary and replication server too. postgresql.conf configuratioj file on replication server shared_preload_libraries = '' is empty on replication server. In case some scenario which will include switchover or failover to replication server. How it will act ? Switchover will be successful but new primary node will fail at startup process because shared_preload_libraries is empty but extensions are created in database? Or it's better to pre-configure same extensions into shared_preload_libraries parameter on replication server? Thank you in advance, Marian Pompura
