Thread: pgsql: Fix bugs in polymorphic-argument resolution for multiranges.
Fix bugs in polymorphic-argument resolution for multiranges. We failed to deal with an UNKNOWN-type input for anycompatiblemultirange; that should throw an error indicating that we don't know how to resolve the multirange type. We also failed to infer the type of an anycompatiblerange output from an anycompatiblemultirange input or vice versa. Per bug #17066 from Alexander Lakhin. Back-patch to v14 where multiranges were added.
