suggestion: default to text type ('character varying') and overload your
prepare method to allow a vector of types for special cases. It follows
that if you don't know what type you are dealing with than it gets dealt
with as a string.

Question: what is the relevance of the binary protocol, are you trying
to send/fetch binary data via the command interface?
