PostgreSQL 14 press release draft

Hi,

Attached is a copy of the first draft for the PG14 press release.

This brings together highlights of many of the features in the upcoming
PostgreSQL 14 release while providing context on their significance.
With the plethora of new features coming in PostgreSQL 14, it is
challenging to highlight them all, but the idea is to give a glimpse of
what to expect in the new release.

Feedback on the release is welcome. However, please provide your
feedback on the release no later than **Thu, Sep 23, 2021 @ 18:00 UTC**.

Thanks,

Jonathan
