=============================
The PostgreSQL Global Development Group announces that the first beta release of
-PostgreSQL 13 is now available for download. This release contains previews of
-all features that will be available in the final release of PostgreSQL 13,
-though some details of the release could change before then.

In the spirit of the open source PostgreSQL community, we strongly encourage you
-to test the new features of PostgreSQL 13 in your database systems to help us
-eliminate any bugs or other issues that may exist. While we do not advise you to
-run PostgreSQL 13 Beta 1 in your production environments, we encourage you to
-find ways to run your typical application workloads against this beta release.

Your testing and feedback will help the community ensure that the PostgreSQL 13
release upholds our standards of providing a stable, reliable release of the
world's most advanced open source relational database. You can read more about

### Functionality
-There are many new features that improve the overall performance of
-PostgreSQL 13 and make it easier to work with simple and complex workloads.
+There are many new features in PostgreSQL 13 that help improve the overall
+performance of PostgreSQL while making it even easier to develop applications.
-On the performance front, B-tree indexes, the standard index of PostgreSQL,
-received improvements to how duplicate data is handled in the index. This helps
-to shrink the index size and improve the speed of lookups, particularly for
-indexes that have significant duplicates.
+B-tree indexes, the standard index of PostgreSQL, received improvements for
+how they handle duplicate data. These enhancements help to shrink index size and
+improve lookup speed, particularly for indexes that contain many repeat values.
PostgreSQL 13 adds incremental sorting, which accelerates sorting data when
-existing data in a query is already sorted. Queries with OR clauses or IN/ANY
-constant lists can now make use of extended statistics, created with
-`CREATE STATISTICS`, which can lead to better planning and performance gains.
+existing data in a query is already sorted. Additionally, queries with OR
+clauses or IN/ANY constant lists can use extended statistics (created via
+`CREATE STATISTICS`), which can lead to better planning and performance gains.
PostgreSQL 13 can now use disk storage for hash aggregation (used as part of
aggregate queries) with large aggregation sets.
`BEFORE` row-level triggers, and a partitioned table can now be fully replicated
via logical replication without having to publish individual partitions.
-PostgreSQL 13 brings more convenience to writing queries and introduces features
-such as `FETCH FIRST WITH TIES` that will return any additional rows that match
-the last row. There is also the addition of the ".datetime" function for
-jsonpath queries, which will automatically convert a date-like or time-like
-string to the appropriate PostgreSQL date/time datatype. It is also even easier
-now to generate random UUIDs, as the `gen_random_uuid()` can be used without

having to enable any extensions.
### Administration
One of the most anticipated features of PostgreSQL 13 is the ability for the
`VACUUM` command to process indexes in parallel. This functionality can be
-accessed with the new `PARALLEL` option on the `VACUUM` command (or `--parallel`
-on `vacuumdb`) allows you to specify the number of parallel workers to use for
-vacuuming indexes. Note that this does not work with the `FULL` option.

+`--parallel` on `vacuumdb`), which allows you to specify the number of parallel
+workers to use for vacuuming indexes. Note that this does not work with the

-The `reindexdb` command can now benefit from parallelism too: the new `--jobs`
-flag lets you specify the number of parallel workers to use when reindexing a
-database.
+The `reindexdb` command has also added parallelism with the new `--jobs` flag,
+which lets you specify the number of concurrent sessions to use when reindexing
+a database.
PostgreSQL 13 introduces the concept of a "trusted extension", which allows for
a superuser to specify extensions that a user can install in their database so
long as they have a `CREATE` privilege.
-This release includes more ways to track what is going on within a PostgreSQL
-database, as PostgreSQL 13 can now track WAL usage statistics and the progress
-of streaming `pg_basebackup`s, and the progress of an `ANALYZE` command.
+This release includes more ways to monitor actibity within a PostgreSQL
+database: PostgreSQL 13 can now track WAL usage statistics and the progress of
+streaming `pg_basebackup`s, and the progress of an `ANALYZE` command.
`pg_basebackup` can also generate a manifest that can be used to verify the
integrity of a backup using a new tool called `pg_verifybackup`.
-`pg_dump` now includes the `--include-foreign-data` flag that, if set, will
-include data from servers referenced by foreign data wrappers in the dump.
+A new flag for `pg_dump`, `--include-foreign-data`, includes data from servers
+referenced by foreign data wrappers in the dump output.
The `pg_rewind` command also has improvements in PostgreSQL 13. In addition to
-`pg_rewind` automatically performing crash recovery, you can now configure use
-it to configure standby PostgreSQL instances using the `--write-recovery-conf`
-flag. `pg_rewind` can also use the `restore_command` of the target instance to
-fetch needed write-ahead logs.

### Security
release, introducing several features to help further deploy PostgreSQL safely.
libpq, the connection library that powers `psql` and many PostgreSQL connection
-drivers, added several new parameters to help secure connections. PostgreSQL 13
-introduces the `channel_binding` connection parameters, which lets a client
-specify that they want to require the channel binding functionality as part of
-SCRAM. Additionally, a client that is using a password protected TLS certificate
-can now specify its password using the `sslpassword` parameter. PostgreSQL 13
-also adds support for DER encoded certificates.

enhancements to how it can secure connections, including the ability to use
Additionally, unprivileged accounts can now connect to another PostgreSQL
database via the `postgres_fdw` without using a password.
+### Other Highlights

PostgreSQL 13 continues to improve operability on Windows, as now users who
run PostgreSQL on Windows now have the option to connect over UNIX domain
sockets.

+The PostgreSQL 13 documentation adds a [glossary](https://www.postgresql.org/docs/devel/glossary.html)

database concepts. This coincides with a significant rework in the display of
functions and operators in tables, which helps to improve readability both on
the web and in the PDF documentation.

-partitioning of the "accounts" table that it uses, making it easier to benchmark
-workloads involving partitions.
