Re: Three Variations of postgresql.conf
Oops, I forgot to mention pg_initicluster, which is used to initiate the various version/cluster combinations in Ubuntu.
It makes it easier to have several versions and clusters on the same server, albeit that is not what most people/companies usually do.Ver Cluster Port Status Owner Data directory Log file
9.1 prod 5432 online postgres /var/lib/postgresql/9.1/prod /var/log/postgresql/postgresql-9.1-prod.log
9.1 dev 5433 online postgres /var/lib/postgresql/9.1/dev /var/log/postgresql/postgresql-9.1-dev.log
9.4 prod 5435 online postgres /var/lib/postgresql/9.4/prod /var/log/postgresql/postgresql-9.4-prod.log
9.4 dev 5436 online postgres /var/lib/postgresql/9.4/dev /var/log/postgresql/postgresql-9.4-dev.log
9.4 qa 5437 online postgres /var/lib/postgresql/9.4/qa /var/log/postgresql/postgresql-9.4-qa.log

To see the ACTUAL clusters installed, and the LIVE config directories,
you use
pg_lsclusters.
Actually:
aklaver@arkansas:~$ pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
9.3 main 5432 down postgres /var/lib/postgresql/9.3/main /var/log/postgresql/postgresql-9.3-main.log
9.4 main 5434 online postgres /var/lib/postgresql/9.4/main /var/log/postgresql/postgresql-9.4-main.log
You get the $DATA directories and the log files. The config directories are in /etc/postgresql/*
pg_ctlclusters then can control each individual cluster
So, for example, since apparently you have the 9.4 version of PostgreSQL,
pg_ctlcluster 9.4 main status
would probably show you that the 9.4 version of PostgreSQL is active and
will also show you the command line arguments used to start it.

FWIW, I would imagine that /usr/lib/tmpfiles.d/postgresql.conf is
a configuration file for the system's tmp-file-cleaner daemon
(probably telling it not to flush some postgres-related files),
not a PG config file at all. If you look into it you'll likely
find that it doesn't look anything like PG configuration data.
As already noted, postgresql.auto.conf is not for hand-editing.
