+/**
+ * sfPostgreSQLDatabase provides connectivity for the PostgreSQL brand database.
+ *
+ * <b>Optional parameters:</b>
+ *
+ * # <b>database</b>   - [none]      - The database name.
+ * # <b>host</b>       - [localhost] - The database host.
+ * # <b>method</b>     - [normal]    - How to read connection parameters.
+ *                                     Possible values are normal, server, and
+ *                                     env. The normal method reads them from
+ *                                     the specified values. server reads them
+ *                                     from $_SERVER where the keys to retrieve
+ *                                     the values are what you specify the value
+ *                                     as in the settings. env reads them from
+ *                                     $_ENV and works like $_SERVER.
+ * # <b>password</b>   - [none]      - The database password.
+ * # <b>persistent</b> - [No]        - Indicates that the connection should be
+ *                                     persistent.
+ * # <b>port</b>       - [none]      - TCP/IP port on which PostgreSQL is
+ *                                     listening.
+ * # <b>username</b>       - [none]  - The database username.
