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.

 
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?
