Introduction

Note: This extension is not available on Windows platforms.

This module provides an additional session save handler for the session module using » PostgreSQL as a storage system. A user-level session storage function may also be used - session_set_save_handler(), but this module is written in C and therefore could be twice as fast, compared to a session save handler written in PHP.

Session PgSQL is designed to scale any size of web sites and offers some advanced features:

• session tables are created automatically
• automatic session table vacuum
• better garbage collection
• multiple PostgreSQL servers support
• automatic database server failover (switching)
• automatic database server load balancing if there are multiple PostgreSQL servers.
• short circuit UPDATE
