Hi,

Attached is the PostgreSQL 16 RC1 release announcement draft.

Currently there is only one item in it, as there was only one open item marked as closed. If there are any other fixes for the RC1 that were specific to v16 and should be included in the announcement, please let me know.

Please provide all feedback no later than August 31, 2023 @ 12:00 UTC (and preferably before that).

Thanks,

Jonathan
The PostgreSQL Global Development Group announces that the first release
candidate of PostgreSQL 16 is now available for download. As a release
candidate, PostgreSQL 16 RC 1 will be mostly identical to the initial release of
PostgreSQL 16, though some more fixes may be applied prior to the general
availability of PostgreSQL 16.

The planned date for the general availability of PostgreSQL 16 is
September 14, 2023. Please see the "Release Schedule" section for more details.

Upgrading to PostgreSQL 16 RC 1
-------------------------------

To upgrade to PostgreSQL 16 RC 1 from earlier versions of PostgreSQL, you will
need to use a major version upgrade strategy, e.g. `pg_upgrade` or
`pg_dump` / `pg_restore`. For more information, please visit the documentation
section on 
[upgrading](https://www.postgresql.org/docs/16/static/upgrading.html):

Changes Since 16 Beta 3
-----------------------

Several bug fixes were applied for PostgreSQL 16 during the Beta 3 period. These
include:

* Fixed performance regression when running `COPY` concurrently on a single
table.

For a detailed list of fixes, please visit the

Release Schedule

PostgreSQL 16 should be made generally available on September 14, 2023.
