pg_type.typreceive and pg_type.typsend
are unused, but I think they should be saved for use as converters
from/to unified binary wire protocol (as their name implies ;) once we
get at it.
The alternative would be yet another system table which would allow us
to support unlimited number of to/from converters for different wire
protocols, but it will definitely be easier to start with
typreceive/typsend.
