Where the PostgreSQL license comes into play is if you make alterations to

Anything contributed to the core PostgreSQL project becomes open-source but
you are permitted to create a commercial port of PostgreSQL with proprietary
code under terms different from those for the core PostgreSQL project. As
your application is most likely NOT one of these ports I'll stop here.
That my be true for MySQL, but I don't think the applies to PostgreSQL. Several companies have forked PostgreSQL into their own proprietary product.
