We are working on a patch (not necessarily to be migrated with the
source code) to allow simplified binding of binary types to native C
types. You can see an older version here: it has examples how to read
off a lot of the types in binary. We should have a new patch in a day
or two that should demonstrate how to read the rest of the types in
binary. We also handled 64 bit ints...
the patch is here
http://archives.postgresql.org/pgsql-patches/2007-12/msg00014.php
if you are patient we can provide examples for all the basic built in
types, including possibly arrays...
