Re: PG11.2 - wal_level =minimal max_wal_senders = 0

Thanks,
I currently have the systems running a parallel pg_dump each night to a separate partition mounted on the VM. Then I perform a full backup of the VM and all mounted drives each night. Would this be affected by disabling wal archiving? I noted that I understood wal archiving was affected in my initial question. But I was not able to see how it could affect my setup. Please school me if I am being naive.

Hi,

Make sure that the new settings of wal_level and max_wal_senders don't interfere with your backup strategy.
The two parameters have an impact on wal archiving as well.

Ben.

In my sandbox it does turn off the logical replication launcher, I just wanted to be sure I am not affecting anything other than replication with this setting.

Quite frankly I've never done, but I don't see why you should not turn it off.
