http://2ndquadrant.com/en/resources/pglogical/Thanks, I found detailed instructions in /usr/share/doc/postgresql-9.5-pglogical/README.md.gzAny chance of putting in online?I see that wal_level = 'logical', and that is a problem for us as we already use wal_level = 'hot_standby' on this installation as it replicates to another server.Is it possible to use pglogical together with hot_standby streaming-replication?Well, the wal_level change is just a matter of database restart: you got to do that once in a while anyway, e.g. for minor version updates. I would expect you only need this wal_level on the walsender side, thus for pglogical_output, the logical decoding plugin.
My point is that we cannot not have streaming-replication, so we need to keep wal_level = 'hot_standby' AFAIU. Is there a way to do both streaming-replication and pglogical for just replicating one of may databases in the same cluster?
