PostgreSQL 18 GA press release draft

Hi,

Attached is a draft of the PostgreSQL 18 GA press release. A few
comments before the ask for reviewing:

* I still need to write up the theme and the quote, which I'll provide
tomorrow after hearing the first round of feedback
* The release is a bit long - this is due in part to what I think is a
lot of really good features in PostgreSQL 18. "Something for everyone"

Please review for the press release for the following:

* Correctness and accuracy of what's described - we want to be
technically correct, but we also need to explain why something matters
to our users.
* Notable omissions (apologies if I missed something, but also note not
everything going to make the cut).
* Features to exclude.
* How easy phrases are to translate / confusing phrases
* Typos.

Like previous years, I won't really look at stylistic remarks, unless it
falls into the "making it simpler to translate / confusing phrase" bucket.

After 2025-09-14 0:00 UTC I won't be able to accept more feedback, as
we'll need to begin the translation process. Anyone who provides
accepted feedback will also get a mention in the press release "thank
you" page[1], which stays up for about a year ;)

Thanks for your help!

Jonathan
