Primarily, it's because postgresql is not a "system" level service. It
is quite possible for ten people using the same server to install their
own copies of postgresql (on differing ports of course) each of which
would be in their own home directories.
In this case, it might well be that each install would need its own
postgresql.conf / pg_hba.conf file to operate properly.
While a service like Bind/DNS, or kerberos, is only usually run one
instance at a time, it isn't all that uncommon for things like apache or
postgresql to be installed and run multiple times. Which is why, one
some installations, apache's conf files are local to the server
directory, and on others (where apache is installed as a system service)
they're in /etc somewhere.
Postgresql knows where it IS by use of either the -D switch or an
envar. Also, by requiring it to be in a directory that belongs to the
process owner and be permed at 700, it is ensured that regular folk AND
sysadmin alike won't go editing it for fun.
