Possibly we could allow for registering both implicit and explicit cast functions for the same combination. Or we could make cast functions take an optional second argument that tells whether the cast is implicit or explicit. We probably also need to take into account the typemod coercion functions that are currently handled in a semi-internal way. (Any formalization of those should probably consider the possibility of allowing typemods on arbitrary types.) Not sure which way to go. -- Peter Eisentraut [EMAIL PROTECTED] ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
