PostgreSQL for WordPress is a special 'plugin' enabling WordPress to be used with a PostgreSQL database.

== Description ==

Wordpress has always been locked into using mysql as its database storage engine.  There is a good discussion of 'why' [in the codex](http://codex.wordpress.org/Using_Alternative_Databases#Solutions/ "Codex Discussion")

But some people would like to use some other databases such as PostgreSQL. There are many different motivations behind this, sometimes people already have PostgreSQL on their server and don't want to install MySQL along PostgreSQL, or simply don't like MySQL and prefer using alternatives.

PostgreSQL for WordPress (PG4WP) gives you the possibility tu install and use WordPress with a PostgreSQL database as a backend.
It works by replacing calls to MySQL specific functions with generic calls that maps them to another database functions.

When needed, the original SQL queries are rewritten on the fly so that MySQL specific queries work fine with the backend database. 

Currently, support is focused on PostgreSQL, but other databases can be added quite easily by providing the appropriate 'driver'.
MySQL driver is enclosed, which just does "nothing".
If you need/wish support for another database, please feel free to contact the author, writing a driver is not really hard if you know a bit about SQL and the database you want support for.

== Installation ==

This plugin can't be enabled through the control panel.
You have to install it before setting up your WordPress installation for things to work properly. 

This section describes how to install the plugin and get it working.
This is because the database needs to be up and running before any plugin can be loaded.

1.	Unzip the files and put the `pg4wp` directory in your `/wp-content/plugins` directory.

1.	Copy the `dp.php` from the `pg4wp` directory to `wp-content`
	
	You can modify this file to configure the database driver you wish to use
	Currently you can set 'DB_DRIVER' to 'pgsql' or 'mysql'
	
	You can also activate DEBUG logs

1.	Point your Web Browser to your wordpress installation and go through the traditional WordPress installation routine.
