I suggest you use libpq (C), libpq++ (C++), Pg.pm (Perl), etc... There are
already interface libraries for this already. Use one of those.

If you really want to do it, I don't know if there is an actual description
but there is always the source.

This will be probably be a very bad idea... One should use the libraries.
The way I would go about this would be reading the source code of one of the
libraries. I think libpq source is quite clear and has lots of comments.

Have you tried the docs?  There is a protocol description in there.

Also look at the source code for the various client interfaces (libpq,
the JDBC driver, etc).
