If you are installing on a PostgreSQL Database, you need to do the following steps:

1. Create a database for the installer to connect to.
2. Create a schema within that database called mediawiki.
3. Install tsearch2 into your database (needed for full text searching)

Notes:
A. The current code is designed to run with an ISO datestyle, if you are using some other datestyle, you will need to modified the code or modify your datestyle. 

B. Some known bugs exist, please check http://pgfoundry.org/tracker/?atid=534&group_id=1000124&func=browse
