Surely there is a way to ship type info, even for UDT's (user defined
types) as nowadays most big databases support those.

I remember someone started cleaning up IO in order to move it into a
separate module with the aim of making multiple implementations (RDA,
TDS, XML, native JDBC wire protocol if it ever becomes a reality, etc.)
possible.
While not exactly pertinent to new wire protocol this effort if
completed would make it much easier to have backwards compatibility on
the wire level.
