Re: How to test replication without doing a failover

How do I test and confirm whether replication is working or not besides depending on just running the SQL below?

select pg_is_in_recovery() ;

select * from pg_stat_replication ;

Is it possible to force/initiate a log transaction and see if that gets replicated or not? I mean for example on Oracle we can do a switch logfile and check if that log gets shipped across and applied on the standby, is there something similar in PostgreSQL?

You can (usually) access the replica in read-only mode

So, what I do is do a transaction on the master and see if it appears on the replica. On a live database that often happens automatically, so I just look at, for instance, the latest entry in a busy table on the master, and check it's the same on the replica. If you do this a couple of times as things change on the master, then you'll know whether or not it's replicating properly
