No, it's easier to hack postgres, as the database is running
as the postgres user. If you allow something like PgPerl, it's
even trivial. The PgPerl script runs as user postgres, and can
trojan e.g. the psql executable. The next time someone (perhaps
even root ... ) runs psql, they're 0wned.
Now it's not that bad an idea to install postgres as a non-root
user .. but use a DIFFERENT account to actually start and run
postgres. That way your binaries are protected.
E.g. install postgres as user 'pgbin', so that all binaries are
owned by 'pgbin', then run it as user 'postgres'.
