Tom Lane 75c46149fc Clean up planner confusion between ncolumns and nkeycolumns. ... We're only going to consider key columns when creating indexquals, so there is no point in having the outer loops in indxpath.c iterate further than nkeycolumns. Doing so in match_pathkeys_to_index() is actually wrong, and would have caused crashes by now, except that we have no index AMs supporting both amcanorderbyop and amcaninclude. It's also wrong in relation_has_unique_index_for(). The effect there is to fail to prove uniqueness even when the index does prove it, if there are extra columns. Also future-proof examine_variable() for the day when extra columns can be expressions, and fix what's either a thinko or just an oversight in btcostestimate(): we should consider the number of key columns, not the total, when deciding whether to derate correlation. None of these things seemed important enough to risk changing in a just-before-wrap patch, but since we're past the release wrap window, time to fix 'em.
