I didn't realize the server lacked binary support for some types. I
guess the driver can disclose this as a caveat emptor when documenting
the binary flag. If you know your particular query workload will not
use certain types, it's not really an issue. If you can't be sure,
that's pretty much a show-stopper unless there's some kind of
automatic fallback to text mode at the driver level, which sounds much
too crazy to be useful.

What issue are you talking about here? Is it related to this:
http://archives.postgresql.org/pgsql-jdbc/2006-12/msg00037.php ? If
so, we don't necessarily need to implement binary parameter input to
support binary result output.
