Sure, if you can cope with binary-oriented data structures being
returned to you by the server. (The actual data is text, as long as you
don't use BINARY CURSORs, but it's wrapped in header and count fields
that are not.) libpq isn't doing anything that's particularly magic.
See the "Frontend/Backend Protocol" chapter of the Developer's Guide for
all the gory details of the client-to-server protocol.
