Probably call it bind_portal though. So far we've aligned the meta
command names with the protocol/libpq names (e.g. \parse instead of
\prepare)

No good reason, just no-one spent the time to implement it. libpq
hasn't implemented most of the somewhat more exotic parts of the
protocol. So yeah, addition is definitely welcome.
