postgresql/contrib/hstore/expected/hstore.out
Teodor Sigaev 754148d81f Add GIN support for pg_trgm. From Guillaume Smet <guillaume.smet@gmail.com> 
with minor editorization by me.

Hstore improvements
* add operation hstore ? text - excat equivalent of exist()
* remove undocumented behaviour of contains operation with NULL value
* now 'key'::text=>NULL returns '"key"=>NULL' instead of NULL
* Add GIN support for contains and exist operations
* Add GiST support for exist operatiion
* improve regression tests
