I guess Marko will be able to take that responsibility, as he has been doing for pg_crypto for years, an recently also pl/python to some degree. tsearch lived in contrib for quite long, evolving a lot and going through a big morphing when it moved to core. I can't see anything nearly as big happening to txid/snapshot types. ---------------- Hannu
