FWIW, the idea that we're going to develop a built-in provider seems to be solid, for the reasons Jeff mentions: it can be stable, and under our control. But it seems like we might need built-in providers for everything rather than just CTYPE to get those advantages, and I fear we'll get sucked into needing a lot of tailoring rather than just being able to get by with one "vanilla" implementation. -- Robert Haas EDB: http://www.enterprisedb.com
