That's true. however, PostgreSQL ships by default with access mode set
to "trust", which means you don't *need* a password. And I bet you'll
find the user being either "postgres" or "pgsql" in 99+% of all
installations.
We do, however, ship with network access disabled by default. Which
means a worm can't get to it, until you enable that. But if you enable
network access, and don't change it from "trust" to something else (such
as md5), then you're wide open to this kind of entry.
(Just create an untrusted PL and hack away - assuming those binaries are
inthere, but I bet they are in most installations)
