Overloading SET to handle both variables and GUCs seems likely to
create problems, possibly including security problems.  For example,
maybe a security-definer function could leave behind variables to
trick the calling code into failing to set GUCs that it intended to
set.  Or maybe creating a variable at the wrong time will just break
things randomly.
