Adjust OR indexscan logic to not generate redundant condition-free OR
indexscans involving partial indexes. These would always be dominated
by a simple indexscan on such an index, so there's no point in considering
them. Fixes overoptimism in a patch I applied last October.

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match
