Thanks, I found detailed instructions in /usr/share/doc/postgresql-9.5-pglogical/README.md.gz
Any 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.
