Log Message:
-----------
Fix ginint4_queryextract() to actually do what it was intended to do for an
unsatisfiable query, such as indexcol && empty_array. It should return -1
to tell GIN no scan is required; but silly typo disabled the logic for that,
resulting in unnecessary "GIN indexes do not support whole-index scans" error.
Per bug report from Jeff Trout.
Back-patch to 8.3 where the logic was introduced.
