Hmph.  The code thinks

     * OTHERS is represented as code 0 (which would map to '00000', but we
     * have no need to represent that as an exception condition).

but it evidently didn't consider the possibility of a user writing
'00000'.  I'm more inclined to consider this a bug and change plpgsql
to use something else internally to represent OTHERS.  We could use
-1, which AFAICS cannot be generated by MAKE_SQLSTATE.
