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
