OK, you look at your postgresql.conf file, and it says the data is in
/var/data, but the postgresql.conf file was found via PGDATA, so it is
ignored, and the directory is /var/local/pgsql. That seems confusing
because someone looking at the file sees the wrong information.
For me, having a config file that both "is found" with ignored values,
and another mode where the config file points to everything seems
strange. Does any other OS project do this?
What if someone does -C /var/data/postgresql.conf, and postgresql.conf
say to use /usr/local/data for data, what do we do?
