Re: Recovering standby from primary archived WAL segments

Hi Ron,

 

I test it using repmgr. So, when i close the postgres and repmgr services at the standby site, as i understand, repmgr drops it's replication slot so there is no wal accumulation in pg_wal at primary site but archiving is working well because it is enabled.

 

Thanks for response,

 If it is possible, how primary and/or standby servers must be configured?

 Set "restore_command" on the standby.

When using physical replication and a replication slot still exists in
pg_replication_slots, won't the WAL files "just" accumulate in pg_wal/ until
Pg on the replica is restarted?  (I just tested that, and it seems to work.)
