With David's recent fixes to allow telling BuildTupleHashTableExt
what input slot type to expect, it's possible to remove the per-row
slot type conversions I was doing before. So here's an updated
patchset with that done.
The common_result_slot_type() function I wrote here perhaps
should be made generally available, but I didn't do that yet.
0002-0005 are the same as before.
regards, tom lane
