PostgreSQL is often compared to MySQL when considering an open source relational database system. While PostgreSQL is known for its comprehensive feature rich database system, MySQL is popular due to its speed and ease of use. Here we will discuss communication protocol for PostgreSQL Database Administration.
PostgreSQL employs a message based protocol for communication in the database between backend and frontend. It is implemented on TCP/IP as well as on Unix domain sockets. The frontend begins by opening a connection to and sending a start up packet to the server. It includes username and the database which user is trying to access. The server uses this information and checks whether it requires the user to send further information to complete authentication.
Once the server verifies information provided by frontend, it responds back with a message to acknowledge startup success or failure. Server launches a backend process for every new client’s request so as to efficiently serve multiple clients. When frontend wants to disconnect from the server, it sends the requisite packet and quits the connection without waiting for backend to respond.
