Yeah, I'm not terribly for the extension idea.  Robert cited the precedent
of contrib/tsearch2, but I think the history of that is a good argument
against this: tsearch2 is still there 9 years later and there's no
indication that we'll ever get rid of it.  We can let things rot
indefinitely in core too.  If we do ever agree to get rid of the aliases,
stripping them out of pg_proc.h will not be any harder than removing
a contrib directory would be.
