Thread: PostgreSQL 15 release announcement draft

Hi,

Please see the first draft for the PostgreSQL 15 release announcement. 
This is the announcement that goes out when we ship 15.0.

A few notes on the first draft:

1. I have not put in any links yet -- I want to ensure the document is 
close to being static before I add those in.

2. I have left in a blurb about SQL/JSON while awaiting the decision on 
if the feature is included in v15.

Please provide feedback no later than 2022-09-10 0:00 AoE[1]. After this 
date, we will begin assembling the presskit that includes the translations.

Thanks,

Jonathan

Thanks. I've attached an updated version that includes other feedback.

Here is a (penultimate?) draft that includes URLs. Please provide any 
additional feedback no later than 2022-09-14 0:00 AoE. After that, we 
will begin the translation process.

Thanks,

Jonathan

We avoid the term "column filtering" here; we talk about column lists.
Maybe it could be "This release introduces row filtering for publishers
and the ability to specify an optional column list for each table".
Also, there are docs to this feature:
https://www.postgresql.org/docs/devel/logical-replication-col-lists.html

It's very strange to have jsonlog and pg_walinspect in the same
paragraph.  Also, pg_walinspect isn't either logging or configuration.
Maybe put it under "other notable changes"?

I can update this -- will do so in the next pass.

Are they backpatched? They don't appear to be here, and a quick scan of 
REL_15_STABLE doesn't seem to show them:

Agree that it's strange to put them together. That said, WAL is a form 
of logging (and a very important one at that ;)

I'm fine with pushing it into "other notable changes". Will update with 
another draft later.

I've made changes per the feedback from you, Peter, & Justin.

I did a better scan and saw it was backpatched here, post Beta 4 tag[1]. 
I captured the link in the docs, but will double-check once RC1 is out.

Please review and let me know your thoughts.

Thanks,

Jonathan
