Yes, that's right. A large volume of code currently proposed for hstore2 is much less valuable than those operators sufficient to implement the hstore2 opclasses. If you assume that hstore will become a legacy extension that we won't add anything to (including everything proposed in any patch posted to this thread), and jsonb will go in core (which is of course more or less just hstore2 with a few json extras), the amount of code redundantly shared between core and an unchanged hstore turns out to not be that bad. I hope to have a precise answer to just how bad soon. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
