postgres/contrib/btree_gin/expected/date.out
Tom Lane fc896821c4 Add more cross-type comparisons to contrib/btree_gin. 
Using the just-added infrastructure, extend btree_gin to support
cross-type operators in its other opclasses.  All of the cross-type
comparison operators supported by the core btree opclasses for
these datatypes are now available for btree_gin indexes as well.
