Fix planner and rewriter to follow SQL semantics for tables that are
mentioned in FROM but not elsewhere in the query: such tables should be joined over anyway. Aside from being more standards-compliant, this allows removal of some very ugly hacks for COUNT(*) processing. Also, allow HAVING clause without aggregate functions, since SQL does. Clean up CREATE RULE statement-list syntax the same way Bruce just fixed the main stmtmulti production. CAUTION: addition of a field to RangeTblEntry nodes breaks stored rules; you will have to initdb if you have any rules.
