You should look at your postgres logs, which will likely tell you
what the real problem is, and then read

http://www.ca.postgresql.org/users-lounge/docs/7.2/postgres/postmaster-start.html#POSTMASTER-START-FAILURES

(sorry bout the long line) and associated bits there.  It seems
likely that you haven't changed the configuration at all; you'll be
very unhappy with the performance that way.  You certainly want at
least a few thousand shared buffers, if nothing else.
