UUID datatype and GIST index support - Mailing list pgsql-general

Is there maybe GIST support patch for UUID datatype?

I do not it it concretly just for UUID column... it is more because of I need it in EXCLUDE constraint...

CREATE TABLE test_exclude

{

id serial NOT NULL,

guid uuid NOT NULL,

valid_period period NOT NULL,

CONSTRAINT "test_excludepk" PRIMARY KEY (id),

EXCLUDE USING gist (guid WITH =. valid_period WITH &&) --for the same guid, period must not overlap...

}

Thanks,

Misa
