Re: PG 9.1 regression / row comparison?

I've actually traced it down to btree_gist. Not sure if this is the expected behavior:

test =# select row(1,2) <> row(1,2);
ERROR:  could not determine interpretation of row comparison operator <>
LINE 1: select row(1,2) <> row(1,2);
                        ^
HINT:  Row comparison operators must be associated with btree operator families.

test=# drop extension btree_gist cascade;
NOTICE:  drop cascades to constraint test_period_excl on table test.test_revs
DROP EXTENSION
test =# select row(1,2) <> row(1,2);
 ?column? 
----------
 f
(1 row)
