Fix inconsistent decisions about NOMATCH vs UNSUPPORTED result codes. If we're going to cater for partkeys that have the same expression and different collations, surely we should also support partkeys with the same expression and different opclasses. Clean up shaky handling of commuted opclauses, eg checking the wrong operator to see what its negator is. This wouldn't cause any actual bugs given a sane opclass definition, but it doesn't seem helpful to expend more code to be less correct. Improve handling of null elements in ScalarArrayOp arrays: in the "op ALL" case, we can conclude they result in an unsatisfiable clause. Minor cosmetic changes and comment improvements. |
