Hello,
It seems that in some (recent? all?) versions of the PGDG Redhat/CentOS
RPMs pg_ctl and service (init.d) don't play well together.
As an example:
-bash-4.1$ id
uid=26(postgres) gid=26(postgres) groups=26(postgres),500(efm)
-bash-4.1$
-bash-4.1$ psql
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
-bash-4.1$
-bash-4.1$ pg_ctl start
server starting
-bash-4.1$ exit
logout
[root@centos6-soe /]#
[root@centos6-soe /]# service postgresql-9.4 status
postgresql-9.4 is stopped
It seems like this is because of pg_ctl and the init.d script using
different lockfiles / pidfiles. This can be fixed by doing the following:
1. Making a directory for locks and pid files (in /var/lock/subsys and
/var/run) and setting it to be owned by postgres
2. Setting unix_socket_directories in postgresql.conf to use the lock
directory by default.
3. Setting external_pid_file in postgresql.conf to use the /var/run
directory by default
4. Setting the init.d script to write the lockfile in the same way
pg_ctl does
Is this something that could change in the future (or is there a reason
this is a bad idea)? I'm happy to provide diffs to get to a working state
if that helps.
Cheers,
James Sewell,
PostgreSQL Team Lead / Solutions Architect

Well, I would love to see the patch. Seems useful to me.
