2020-02-13 Press Release Draft

Hi,

Attached is a draft for the 2020-02-13 press release. I would appreciate
any review for accuracy, notable omissions, and the inevitable typos I
tend to have on drafts (even though I do run it through a spell
checker). There were over 75 fixes, so paring the list down was a bit
tricky, and I tried to focus on things that would have noticeable user
impact.

As noted in other threads, this is the EOL release for 9.4. In a
departure from the past, I tried to give a bit of a "tribute" to 9.4 by
listing some of the major / impactful features that were introduced, the
thought process being that we should celebrate the history of PostgreSQL
and also look at how far we've come in 5 years. If we feel this does not
make sense, I'm happy to remove it.

While I'll accept feedback up until time of release, please try to have
it in no later than 2020-02-13 0:00 UTC :)

Thanks,

Jonathan
