Yes you could. The original Postgres developers (or at least some of
them) did just that in founding Illustra. They sold the company a
couple of years later for $50M US to Informix.

The original sources, and the modified sources *that we know about*
(someone could have and probably has taken the source code, modified
it, and not contributed back the changes) are always fair game to be
taken out of open source status. That is an artifact or benefit or
downside of the BSD license, depending on your PoV.

The original copyrights are still valid and travel with the code.
However, afaict they are designed to release UC Berkeley from
liability and to preserve some credit for the original work, not to
allow Berkeley to assert ownership control over derivative sources
(into which category I think the current PostgreSQL tree falls, so to
I think Marc is concerned that there be someone or something able to
represent the current code tree, and to prevent hijacking of the
PostgreSQL (and perhaps Postgres) names from this open source group.
He has been consistantly adamant about preserving the BSD copyright,
which leave the maximum flexibility for the use of the code tree
basically for any purpose by anyone. That isn't quite the same goal of
GPL, but check the archives for threads which cover these topics
