PostgreSQL 11 RC1 Released!

Jonathan S. Katz-3
The PostgreSQL Global Development Group announces that the first release
candidate of PostgreSQL 11 is now available for download. As a release
candidate, PostgreSQL 11 RC 1 should be identical to the initial release
of PostgreSQL 11, though some more fixes may be applied prior to the
general availability of PostgreSQL 11.

Upgrading to PostgreSQL 11 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.

Changes Since 11 Beta 4
-----------------------

There have been many bug fixes for PostgreSQL 11 reported during the
Beta 4 period and applied to this release candidate. These fixes include:

* Fix a crash that occurred with event triggers on partitioned tables
* Ensure the `transaction_timestamp` function returns an updated
timestamp in
a stored procedure if it is called after a transaction is committed
* Disallow multiple primary keys to be created on partitions
* Fix for `ALTER TABLE .. ATTACH PARTITION`

For a detailed list of fixes, please visit the open items page:

Release Schedule
----------------

This is the first release candidate for PostgreSQL 11. Unless an issue
is discovered that warrants a delay or to produce an additional release
candidate, PostgreSQL 11 should be made generally available on October
18, 2018.
