I would expect the primary *performance* value in an "hstore extension" to come from things that allow accessing data without needing to "unbox" it. (I remember the concept of unboxing from APL; it seems to have been subsumed by object oriented terminology... http://en.wikipedia.org/wiki/Object_type_%28object-oriented_programming%29#Unboxing) The big "win" comes not as much from type matching (which seems to me like a morass, as you'll need the zillion Postgres types to cover all the cases) as it comes from avoiding the need to take the "blobs" of tuple data and re-parse them. -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?" -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
