[GENERAL] Comunication protocol
Hi everyone: I have a question. I think it's so simple to answer but I don't know anything about that. I want to know what is the comunication protocol among PostgreSQL database server and an application server like Apache. I have to know that because I'm designing a simple deployment diagram and I just need it for finish. Thanks in advance.

Re: [GENERAL] Comunication protocol
Thanks Tom for your response so fast. I'm reading r ight now and I found something but I didn't understood very well. In the documentation says that the protocol we're talking about is supported over TCP/IP family protocols, but doesn't says what exactly protocol is it? I want to know something more specific. Thanks again.

Re: [GENERAL] Comunication protocol
Maybe you can use a software like Wireshark in your network and provoke a connection between your PostgreSQL server and Apache server, and when you see the results of traffic monitoring on Wireshark you can see more specific details about the protocol.

Re: [GENERAL] Comunication protocol
Thanks Oscar. I'm going to try your suggestion but I get a problem. I get the database server and apache server in the same PC because the system what I'm building is in development phase. Do you think that is a problem for wireshark?

From the documentation link that Tom provided you might have read that the frontend/backend protocol which the database server and clients connecting to it use - is a message based protocol in which the messages are exchanged over either TCP/IP connection or UNIX doman sockets. If you configure your client to use loopback interface (127.0.0.1) to connect to the database you would be looking at a TCP/IP connection, so probably manageable by Wireshark. Though, I would suggest reading the protocol description in the documentation so that you understand distinct phases of connection and subsequent operation over the established connection. -- Amit Langote -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
