The above could easily be misinterpreted. I believe the point Thomas
meant to make is that anyone is free to make a derivative version that
they choose not to release as open source. It does *not* mean that
someone can take away your right to use existing code that was already
released with a Berkeley-style license.

Right, and I think that it's past time that the Postgres group (in
the person of PG Inc, or some other entity if that's what a majority
want) explicitly make the same statements that UC Berkeley has made.
Anyone here want to be on the hook for liability when some big
company's database crashes? Not me...

That's actually quite a separate issue. Trademarking the name
"PostgreSQL" might be a good idea to prevent some random bozo from
claiming ownership of it. (In reality, I think any attempt by
someone else to register that name as a database trademark at this
point could easily be shot down, but it would be far cheaper to
register the mark pre-emptively than to file suit against someone's
predatory registration.) Yet ... on the other hand, if it were a
trademark then someone *could* buy it off PG Inc. If that happened,
we (the community) would still have the rights to use the Postgres code,
but we'd have to find another name for it ;-).
