These files will allow you to use PostgreSQL as a backend of osCommerce
As for now the status is 'mostly working' as it is not well tested and very fresh.
Bugs reports welcome.

There are some hacks but generally changes are small sql fixes, 
which will work with MySQL as well so by replacing database.php one 
can chose between PostgreSQL and MySQL.

I also created some compatibility sql functions.
These implement mysql's not standart functions.
In fact they use in most cases there are ANSI SQL functions supported 
by both PostgreSQL and MySQL.

As for now, the postgresql import file is a more or less exact copy of mysql version.
As a result there are no foreign key constraints.
Also osCommerce in some cases tries to insert '0' instead of 'NULL' 
so some constraints would make osCommerce crush.

Install:
Just copy the database.php to includes/functions in catalog i admin
from extras/pgsql directory.
Install does not work so you need to import the oscommerce file manually.

Not working:
 * Install
 * Admin->Tools->Backup
