You made the same mistake I did in reading this. The statement that
David made is correct, but you have to read it carefully; here it is
with emphasis:

"Anything *contributed* to the core PostgreSQL project becomes
open-source but..."

In other words, if you send us a patch and we like it and add it to PG,
it becomes part of PG which is released under the BSD license. Were
something submitted under some other license, it'd be hard to call it a
contribution to PG and it'd be pretty unlikely to get committed anyway.

Thanks,
