PostgreSQL 7.3.7 has a risk of data loss explained here:
http://archives.postgresql.org/pgsql-hackers/2004-10/msg00464.php

In addition there are two minor security issues reported to us by iDEFENSE; these were 
judged too minor to warrant assigning CVE names, but they should be fixed anyway.  Both 
are escalation-of-privilege issues that might allow the postgres user to obtain root.  The 
first is that "pg_ctl start" executes a shell command using text obtained from a postgres-
owned configuration file.  This is only a minor risk because "pg_ctl start" should never be 
run as root anyway; but possibly a sysadmin unfamiliar with Postgres could be tricked into 
doing it.  The appropriate fix is to disallow pg_ctl from running as root.  The second issue 
is that the postgresql init script executes a "chown" as root without sufficient care about 
what is being chown'ed; a nefarious postgres user could install a symlink to cause any 
desired file to be chown'd to postgres.  (This was judged a minor issue only because 
installation of the symlink would break the Postgres installation, and thus would be rather 
unlikely to go undetected until next system reboot.)

The first two issues are solved in the upstream Postgres 7.3.8 release, which we should 
upgrade to.  The init-script issue we need to fix locally.
