You may do with PostgreSQL what you wish. Change it, sell it, do anything,
and there are no charges or fees to pay under any condition. Here's the key
paragraph:

"Permission to use, copy, modify, and distribute this software and its
documentation for any purpose, without fee, and without a written agreement
is hereby granted, provided that the above copyright notice and this
paragraph and the following two paragraphs appear in all copies."
