Re: Wal streaming

Hi,

I’m using Postgres 17 and the latest versions of repmgr and barman

1. I’m replicating my database to another node using streaming replication. wal_level=replica, hot_standby=on.
2. I’ve got barman running on the primary node locally and have setup the barman config for streaming replication using streaming archiver and backup method Postgres. Previous to this I was using the archive and restore commands in postgresql.conf to use barman-wal-archive|restore to copy the wal files to barman’s wal folder.
3. Barman is on node 1 where the primary is running. The replica database used by repmgr is on node 2.
4. My archive command is still configured to use barman-wal-archive despite having moved to a streaming replication method in barman.

So my question is, can I disable the archive command now that I am using streaming?

Andrew
