This has been discussed and rejected previously. The big strikes
against it are (1) it prevents having more than one PG installation
on the same machine, and (2) it assumes that the DBA and root are
the same person, since files in /etc should generally only be writable
by root.
See the pghackers archives for extensive discussions about config file
locations. There have been several proposals on separating config files
from PGDATA, but none have achieved a consensus agreement as yet.
