... or by many client libraries, though converting hstore values to json notation for output usually takes care of that. I can't help but suspect that hstore will be subsumed by native storage and indexing of json objects, since these are already widely supported in KV or document stores. Of course, that requires that we come to some agreement on how to represent literal scalars for interaction with json, which hasn't seen much progress. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
