Yes that would be the standard approach.  But the Debian package removes pg_ctl from it normal place and wraps it with a perl script in a way that makes it difficult to work with (it doesn’t accept the same arguments):


@Mangnus, can you give me an example of how I might use pg_lsclusters and pg_ctlcluster?  I’ve tried:

pg_ctlcluster 9.4 main start
Error: could not exec   start -D /var/lib/postgresql/9.4/main -l /var/log/postgresql/postgresql-9.4-main.log -s -o  -c config_file="/etc/postgresql/9.4/main/postgresql.conf”

What about if use pg_ctl as the postgres user? That will give you a better idea.

You don't want ot be doing that on a systemd system, but try a combination of pg_lsclusters and pg_ctlcluster. Might be you need to shut it down once that way before it realizes it's down,and then start it back up.
