<para>
This module provides an additional session save handler for the
<link linkend="book.session">session</link>
module using <link xlink:href="&url.pgsql;">PostgreSQL</link> as a
storage system. A <literal>user-level</literal> session storage function may
also be used - <function>session_set_save_handler</function>, but this module is
written in C and therefore could be twice as fast, compared to
a session save handler written in PHP.

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