This would be in plpgsql.

Some other info:

What I'm trying to do is use contrib/userlock to serialize access to a
function. The only effective way to come up with a unique lock number
that I've been able to think of is to use the OID of the function
itself.

What I find somewhat interesting is every other database I've used that
exposes some kind of 'object ID' has a set of functions to map between
an object name and it's ID, and vice-versa. It seems like this is
something that would be good for PostgreSQL to have.
