Hi, I am conducting a benchmark to compare KVP table vs. hstore and got bad hstore performance results when the no. of records is greater than about 500'000. CREATE TABLE kvp ( id SERIAL PRIMARY KEY, key text NOT NULL, value text ); -- with index on key CREATE TABLE myhstore ( id SERIAL PRIMARY KEY, obj hstore NOT NULL ); -- with GIST index on obj Does anyone have experience with that?
