ba398969cd Update contrib/hstore for new GIN extractQuery API.
In particular, make hstore @> '' succeed for all hstores, likewise
hstore ?& '{}'.  Previously the results were inconsistent and could
depend on whether you were using a GiST index, GIN index, or seqscan.

David Wheeler, with one small correction by me.

8327060dc2 Updated expected-output file for hstore.
This is an oversight in my previous patch to deprecate => as an operator
name.  Per buildfarm.

31c47e53aa Rename hstore => text[] operator to %
This is not yet in any released version, so we still have the option to
change the name.  We may want to reserve the token => in a future release.

b17129b589 Remove hstore's text[] => text[] operator.
This is not yet in any released version, so we still have the option to
backtrack.  Instead, document hstore(text[], text[]).  Per discussion.

172eacba43 Assorted improvements in contrib/hstore.
Remove the 64K limit on the lengths of keys and values within an hstore.
(This changes the on-disk format, but the old format can still be read.)
Add support for btree/hash opclasses for hstore --- this is not so much
for actual indexing purposes as to allow use of GROUP BY, DISTINCT, etc.
Add various other new functions and operators.

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

3f16647960 Rename function 'isexists' and 'isdefined' to
'exist' and 'defined' accordingly. Old names
are saved not mentioned in docs - for compatibility
with old applications.
