I know this is a broken install, but postmaster should not segfault when
it can't find a file.

postgres@war PGDATA $ ../pgsql7.3/bin/postmaster
LOG:  load_hba: Unable to open authentication config file
"/usr/local/PGDATA/pgsql7.3/pg_hba.conf": No such file or directory
Segmentation fault (core dumped)
