Please pardon me for jumping in here, but one of the things people
really love about PostgreSQL is that when you reach for something,
it's frequently "just there."

As we're improving enums (allowing them to be altered easily after
creation, etc.), it seems reasonable to provide ways to return them
from all kinds of PLs, including making this easier in C.
