It would be nice if we had a way to generate a lot of similar values for a every data type. Then we could have a regression test which checks for each data type that the hash function matches the equality operator -- and for that matter that the various inequality operators are also consistent. I'm not sure how to generate values though. For a lot of data types it would be hard to generate values densely enough to trigger any bugs. -- greg -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
