I want protocol descriptions of Postgresql 7.1 I mean how Postgres listens
request at default port 5432. If one wants to write to execute some query
using its program(like in C, java) directry by sending data at server socket
5432 then how this task can be achieved. Can anybody tell me from where i
can find this.

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.

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.

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).
