Postgresql falls under an X11 LIKE license, which happens to be the BSD 
license.  Of the links listed, the only definitive one is the one from 
www.postgresql.org

Postgresql is free for use in all instances, commercial or otherwise.  
The only requirements are the ones listed on the licence page you listed. 
I.e. you have to include the copyright notice.

So, it's free as in beer (no cost) and free as in freedom (no restrictions 
on use.)
