Not a lawyer, and all that.

MySQL is GPL licensed, (with a handful of special exceptions).  It's
perfectly free, but if your apps need to 'link' to the code, it needs to
be under a gpl compatible license.  (I'll leave to others to debate what
exactly constitutes linking and what just usage.)

ProstGre is BSD licensed, and the code can be re-used and linked in just
about any way you want (provided attribution)
