Tom Lane 389af07cf0 Clean up rewriter routines to use expression_tree_walker and ... expression_tree_mutator rather than ad-hoc tree walking code. This shortens the code materially and fixes a fair number of sins of omission. Also, change modifyAggrefQual to *not* recurse into subselects, since its mission is satisfied if it removes aggregate functions from the top level of a WHERE clause. This cures problems with queries of the form SELECT ... WHERE x IN (SELECT ... HAVING something-using-an-aggregate), which would formerly get mucked up by modifyAggrefQual. The routine is still fundamentally broken, of course, but I don't think there's any way to get rid of it before we implement subselects in FROM ...		1999-10-01 04:08:24 +00:00
