## E.31. Postgres Pro Standard 10.4.1

Release Date: 2018-05-23

### E.31.1. Overview

This release is based on PostgreSQL 10.4 and Postgres Pro Standard 10.3.2. All changes inherited from PostgreSQL 10.4 are listed in PostgreSQL 10.4 Release Notes. Other major changes and enhancements are as follows:

- Updated the Section F.31 to fix the sorting order for Cyrillic letters Yo and short I. Make sure to run the `REINDEX` command to rebuild indexes that use `mchar` or `mvarchar` types.

- Added full-text search support for the Nepali language into the Snowball and Hunspell dictionaries. (See snowball_ext and Hunspell Dictionaries Modules.)

- Updated jsquery module.

- Updated PTRACK to version 1.6:

  - Now ptrack doesn't track unlogged relations.

- Updated the pg_probackup utility to version 2.0.17, which includes the following new features:

  - `DELTA` mode for incremental backups that reads all data files in the data directory and creates an incremental backup for pages that have changed since the previous backup.

  - New options for `restore` and `validate` commands:

    - `--immediate` option ends recovery as soon as a consistent state is reached.

    - `--recovery-target-action` option specifies the action the server should take when the recovery target is reached.

    - `--recovery-target-name` specifies a named savepoint up to which to restore the cluster data.

    - `--write-recovery-conf` writes a minimal `recovery.conf` in the output directory to facilitate setting up a standby server.

    For details, see pg_probackup.

- Updated `pg_pathman` module to version 1.4.11. As compared to version 1.4.9, the following enhancements were introduced:

  - Fixed an issue with duplicate entries in query results for inherited tables. In general, `pg_pathman` does not support multilevel partitioning.

  - Fixed a spurious `table is being partitioned now` error raised by `partition_table_concurrently()`.

  - Relaxed check constraint handling.

  - Fixed incorrect usage of `memcpy()` in `start_bgworker()`.

  - For a full list of changes, see pg_pathman Wiki.

- Added `pgpro-version` and `pgpro-edition` options to `pg_config`.

- The `recovery.conf` file is now reloaded whenever the main server process receives a `SIGHUP` signal.

- Performed multiple bug fixes in the shared_ispell module.

- On Debian-based systems, renamed the `pg_repack` package from `pg-repack-10` to `pg-repack-std-10`.

- Log files are now automatically reopened when a `SIGHUP` signal is received by the logger process.

- Improved Postgres Pro Standard version for Windows:

  - Fixed an issue with pasting strings that include symbols of different character sets from clipboard to psql on Windows systems.

  - Updated optimization algorithm for default database configuration.

  - You can now turn off configuration optimization when installing Postgres Pro from the command line by setting the `needoptimization` option in the INI file to `0`.

### E.31.2. Migration to Version 10.4.1

If you are upgrading from a Postgres Pro Standard version based on the same PostgreSQL major release, it is enough to install the new version into your current installation directory.

### Important

When upgrading from versions 10.3.2 or lower, you must call the `REINDEX` command for indexes that used `mchar` or `mvarchar` types.

### Important

If you have been using `pg_repack` on Debian-based systems, you have to reinstall its package manually when upgrading to this version since its package got renamed to `pg-repack-std-10`.

To migrate from PostgreSQL or Postgres Pro Standard versions based on any previous PostgreSQL major release, see the instructions in Postgres Pro Standard 10.1.1 Release Notes. If you are opting for a dump/restore, make sure to use the `--add-collprovider` option to correctly choose the collation provider for the migrated database.
