Actually, the latter isn't so.

If Mammoth or Pervasive or such release their own release of
PostgreSQL, nothing has historically mandated that they make that
release available under the BSD license.

Presumably acceptance of the patent would change that.

You and I might not have individual objections to this situation, but
one or another of the companies putting together PostgreSQL releases
very well might.
