+
+ <para>
+  In general, these operator classes will not outperform the equivalent
+  standard btree index methods, and they lack one major feature of the
+  standard btree code: the ability to enforce uniqueness.  However,
+  they are useful for GIN testing and as a base for developing other
+  GIN operator classes.  Also, for queries that test both a GIN-indexable
+  column and a btree-indexable column, it might be more efficient to create
+  a multi-column GIN index that uses one of these opclasses than to create
+  two separate indexes that would have to be combined via bitmap ANDing.
