## E.3. Postgres Pro Standard 10.10.2

Release Date: 2019-10-09

### E.3.1. Overview

This release is based on Postgres Pro Standard 10.10.1 and provides several improvements:

- Added support for CentOS 8.

- The expression comparison function has been reworked to fix bugs and improve support in the future.

### E.3.2. Migration to Version 10.10.2

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.

Since pg_probackup delivery model changed in Postgres Pro Standard 10.7.1, when upgrading from a lower version on ALT Linux and Debian-based systems, run `apt dist-upgrade` (or `apt-get dist-upgrade`) to ensure that all new dependencies are handled correctly. On Windows, you have to run a separate pg_probackup installer to complete the upgrade.

When upgrading from version 10.3.2 or lower, you must call the `REINDEX` command for indexes that used `mchar` or `mvarchar` types. Besides, 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 a Postgres Pro Standard release based on a previous PostgreSQL major version, 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 provider for the default collation of the migrated database.
