Tom Lane 6e07709760 Implement SQL-compliant treatment of row comparisons for < <= > >= cases ... (previously we only did = and <> correctly). Also, allow row comparisons with any operators that are in btree opclasses, not only those with these specific names. This gets rid of a whole lot of indefensible assumptions about the behavior of particular operators based on their names ... though it's still true that IN and NOT IN expand to "= ANY". The patch adds a RowCompareExpr expression node type, and makes some changes in the representation of ANY/ALL/ROWCOMPARE SubLinks so that they can share code with RowCompareExpr. I have not yet done anything about making RowCompareExpr an indexable operator, but will look at that soon. initdb forced due to changes in stored rules.		2005-12-28 01:30:02 +00:00
