pgsql: De-kludge contrib/btree_gin for collations.

De-kludge contrib/btree_gin for collations.

Using DEFAULT_COLLATION_OID in the comparePartial functions was not only
a lame hack, but outright wrong, because the compare functions for
collation-aware types were already responding to the declared index
collation. So comparePartial would have the wrong expectation about
the index's sort order, possibly leading to missing matches for prefix
searches.
