pgsql: Don't try to remove duplicate OR-subclauses in - Mailing list pgsql-committers

Log Message:
-----------
Don't try to remove duplicate OR-subclauses in create_bitmap_subplan and
make_restrictinfo_from_bitmapqual.  The likelihood of finding duplicates
seems much less than in the AND-subclause case, and the cost much higher,
because OR lists with hundreds or even thousands of subclauses are not
uncommon.  Per discussion with Ilia Kantor and andrew@supernews.
