Make psql's "\pset format" command reject non-unique abbreviations.
The previous behavior of preferring the oldest match had the advantage of not breaking existing scripts when we add a conflicting format name; but that behavior was undocumented and fragile (it seems just luck that commit add9182e5 didn't break it). Let's go over to the less mistake- prone approach of complaining when there are multiple matches. Since this is a small compatibility break, no back-patch.
