It certainly seems to come up a lot, but I'm not sure whether the two main use cases -- mapping types into languages, and mapping types into JSON (or XML, as an alternative) -- would have the same solution. A third use case that could be included as well is changing the main text or binary format of a type (e.g., what datestyle does). So instead of having just a hard-coded set of typinput/typoutput, typrecv/typsend, you'd have a catalog of (context, inputfunc, outputfunc) and the context would a language, something json or xml, or a user-settable value. This could become quite complicated, but it sure could solve a lot of issues in one go. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
