I have a PostgreSQL setup with one master and three slaves. It's configured as streaming replication.
Now, I want to replicate only a few tables from the master server to an analytic server using pglogical. For this, we need to enable the logical wal_level
. So how can I enable it without breaking the existing replication?

This is what the documentation says about the topic:
From the text it's not overly clear, but
logical
is the highest level of all, meaning it includes everything thereplica
level does. That means you can safely setwal_level
tological
, it won't break your existing replication.
