Hi,

I=E2=80=99m using Postgres 17 and the latest versions of repmgr and barman

1. I=E2=80=99m replicating my database to another node using streaming repli=
cation. wal_level=3Dreplica, hot_standby=3Don.=20
2. I=E2=80=99ve got barman running on the primary node locally and have setu=
p the barman config for streaming replication using streaming archiver and b=
ackup method Postgres. Previous to this I was using the archive and restore c=
ommands in postgresql.conf to use barman-wal-archive|restore to copy the wal=
 files to barman=E2=80=99s wal folder.=20
3. Barman is on node 1 where the primary is running. The replica database us=
ed by repmgr is on node 2.=20
4. My archive command is still configured to use barman-wal-archive despite h=
aving moved to a streaming replication method in barman.=20

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

Regards
Andrew
