Hi, Attached is a draft for the PostgreSQL 12 RC1 press release. Please let me know if you find any errors or notable omissions.
I'd also like to take this opportunity as a chance to say thank you to everyone for your hard work to get PostgreSQL 12 to this point. I'm personally very excited for what should be yet another fantastic release that will provide a lot of great features and enhancements for our users! Thanks, Jonathan
PostgreSQL 12 RC 1 Released =========================== The PostgreSQL Global Development Group announces that the first release candidate of PostgreSQL 12 is now available for download. As a release candidate, PostgreSQL 12 RC 1 should be identical to the initial release of PostgreSQL 12, though some more fixes may be applied prior to the general availability of PostgreSQL 12. The planned date for the general availability of PostgreSQL 12 is October 3, 2019. Please see the "Release Schedule" section for more details. Upgrading to PostgreSQL 12 RC 1 ------------------------------- To upgrade to PostgreSQL 11 RC 1 from Beta 4 or an earlier version of PostgreSQL 11, you will need to use a strategy similar to upgrading between major versions of PostgreSQL (e.g. `pg_upgrade` or `pg_dump` / `pg_restore`). For more information, please visit the documentation section on [upgrading](https://www.postgresql.org/docs/12/static/upgrading.html). Changes Since 12 Beta 4 ----------------------- There have been many bug fixes for PostgreSQL 12 reported during the Beta 4 period and applied to this release candidate. These include: * Add additional "leakproof" markings to certain string functions to better support nondeterministic collations. This can positively impact the performance of some query plans * Removal of the ECPG `DECLARE STATEMENT` functionality * The ecpglib major version change was reverted * Fix handling of nondeterministic collations with pattern\_ops opclasses For a detailed list of fixes, please visit the [open items](https://wiki.postgresql.org/wiki/PostgreSQL_12_Open_Items#resolved_before_12rc1) page. Release Schedule ---------------- This is the first release candidate for PostgreSQL 12. Unless an issue is discovered that warrants a delay or to produce an additional release candidate, PostgreSQL 12 should be made generally available on October 3, 2019. For further information please see the [Beta Testing](https://www.postgresql.org/developer/beta/) page.
