Re: Allowing GIN array_ops to work on anyarray

The following review has been posted through the commitfest application:
make installcheck-world: tested, passed
Implements feature: tested, passed
Spec compliant: not tested
Documentation: tested, passed

I built and installed (make world / make install-world) github branch REL9_6_STABLE and applied the patch (patch -p1 < patch/gin-true-anyarray-opclass-1.patch).

I then upgraded my development database (postgres 9.5) using pg_upgrade. This database has one table with an UUID array gin index. The database was upgraded correctly to postgresql 9.6 and I was able to successfully connect to it from a web application which uses the database. There were no conflicts so I expect others to be able to upgrade without issues.

I then dropped the database and re-created it... I made sure that I no longer used my prior operator class definition. I re-started my web application and confirmed it works. This verifies the feature works as designed.

The following is no longer required:

CREATE OPERATOR CLASS _uuid_ops DEFAULT
FOR TYPE _uuid USING gin AS
OPERATOR 1 &&(anyarray, anyarray),
OPERATOR 2 @>(anyarray, anyarray),
OPERATOR 3 <@(anyarray, anyarray),
OPERATOR 4 =(anyarray, anyarray),
FUNCTION 1 uuid_cmp(uuid, uuid),
FUNCTION 2 ginarrayextract(anyarray, internal, internal),
FUNCTION 3 ginqueryarrayextract(anyarray, internal, smallint, internal, internal, internal, internal),
FUNCTION 4 ginarrayconsistent(internal, smallint, anyarray, integer, internal, internal, internal, internal),
STORAGE uuid;

I also ran "make installcheck-world" and all the tests passed.

The new status of this patch is: Waiting on Author
