Check the relevant index element in ON CONFLICT unique index inference.
ON CONFLICT unique index inference had a thinko that could affect cases
where the user-supplied inference clause required that an attribute
match a particular (user specified) collation and/or opclass.
infer_collation_opclass_match() has to check for opclass and/or
collation matches and that the attribute is in the list of attributes or
expressions known to be in the definition of the index under
consideration. The bug was that these two conditions weren't necessarily
evaluated for the same index attribute.
