Tom Lane	8a9acd3c41	Teach predtest.c how to reason about ScalarArrayOpExpr clauses as though they were broken-out AND or OR lists. The least grotty way to do this seemed to be to set up a general mechanism for handling nodes as though they were ANDs or ORs. There's no other immediate use for it, but perhaps we might want to use the mechanism someday for things like BETWEEN SYMMETRIC.	20 years ago

Tom Lane	fa63749d21	Fix oversight in indexscan plan creation. I recently added code to use predicate_implied_by() to detect redundant filter conditions, but forgot that predicate_implied_by() assumes its first argument contains only immutable functions. Add a check to guarantee that. Also, test to see if filter conditions can be discarded because they are redundant with the predicate of a partial index.	21 years ago
Tom Lane	d007a95055	Simple constraint exclusion. For now, only child tables of inheritance scans are candidates for exclusion; this should be fixed eventually. Simon Riggs, with some help from Tom Lane.	21 years ago
Tom Lane	2f1210629c	Separate predicate-testing code out of indxpath.c, making it a module in its own right. As proposed by Simon Riggs, but with some editorializing of my own.	21 years ago
