I was hoping it would be acceptable to leave this function in (as well
as the one to get the number of config variables), once it was renamed
to remove the reference to GUC.

Without it, it is impossible for a user function to return a list of
config variables without prior knowledge of the config variable names. I
would still like to have this ability. The only workaround without these
functions is to parse "SHOW ALL" output which is an awfully ugly
alternative.
