PostgreSQL 13 press release draft

Hi,

Attached is a copy of the proposed press release for PostgreSQL 13, with
a link to the current document in our git repository as well[1].

Feedback of course is welcome.

To provide some context on the overall release:

* This follows the previous formats of the press releases to provide
feature highlights and be used as a springboard into discovering the
features.

* The press kit has been slimmed down. This is due to an overall
decrease in actual traffic to the press release through the years,
though downloads themselves have gone up after the release! This likely
due to fragmentation of how people consume PostgreSQL news, as today the
release serves more as a "hey the new PostgreSQL software is available!"

(And yes, according to the stats, PostgreSQL is more popular than ever ;)

This allows us to make the translation effort easier and lower the
overall maintenance efforts of the release.

* I did some research on the contents of the release itself, and it
appears to be comparable to our open source and proprietary database
peers. I did look to see if their releases included user testimonials:
those tended to be in either separate releases or other media.

Given the lack of volunteering for user testimonials over the years and
the time it takes to solicit them, I've dropped those efforts, but if
someone wants to either contribute or provide some and they are
appropriate for the release, I'd be happy to include it.

Anyway, I am personally very excited for the PostgreSQL 13 release :)

If you have any feedback, please provide it **no later than August 30,
2020 AoE**[2] as after that we will need to begin the translation effort.

Thanks!

Jonathan
