Installation

You have to install PG4WP before configuring your WordPress installation for things to work properly. This is because the database needs to be up and running before any plugin can be loaded.

1. Place your WordPress files in the right place on your web server.

2. Download the latest release From the releases page

3. Unzip the files from PG4WP and put the pg4wp directory in your /wp-content directory.

4. Copy the db.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 and/or ERROR logs

5. Create wp-config.php from wp-config-sample.php if it does not already exist (PG4WP does not currently intercept database connection setup).

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