Postgres 16 and pgbackrest 2.52.1 on RHEL 9.4
Is this a potential issue ?
Only if you don't want to be replicating to a standby server.
It has been running for 17 days . ( I have configured WAL replication to a standby server and pgbackrest to a remote server ) is this normal running 17 days START_REPLICATION B5/EE000000 TIMELINE1 active ?
Select more columns, like username,client_hostname and client_addr.
You started replicating to the standby server 17 and a half days ago. This is how PG replicates to the standby server.
Any hints to further trace where the query is executing, what it's trying to perform, how to optimize if this is not normal ? Any guidance is much appreciated..
It's certainly normal if you want to replicate to a standby server.
