Tom Lane c186c93148 Change the planner to allow indexscan qualification clauses to use ... nonconsecutive columns of a multicolumn index, as per discussion around mid-May (pghackers thread "Best way to scan on-disk bitmaps"). This turns out to require only minimal changes in btree, and so far as I can see none at all in GiST. btcostestimate did need some work, but its original assumption that index selectivity == heap selectivity was quite bogus even before this.		2005-06-13 23:14:49 +00:00
