In 7.4 and later the client/server protocol supports binary data
transfer. If you're programming with libpq you can use PQexecParams()
to send and/or retrieve values in binary instead of text.

APIs built on top of libpq or that implement the protcol themselves
might provide hooks to this capability; check your documentation.
What language and API are you using?

Binary transfer sends data in binary, not by automatically converting
to and from text.
