I support Andrew's comment, though might reword it to
"Don't enable anything that gives users programmable features or user
exits by default".
You can't use the builtin encoding functions or non-btree indexes to
access things you are not supposed to.
Anything that is *always* there provides a platform for malware.
I'm not really sure what is wrong with the CREATE LANGUAGE statement
anyway - it is dynamically accessible, so doesn't require changes that
effect other database instance users. I do understand the wish to make
the lives of admins easier, but this isn't a hard thing to do...

Security is everybody's job, not just the OS guys. Personally, I forget
that constantly, but the principle seems clear.
