## E.47. Postgres Pro Standard 9.6.3.2

Release date: 2017-07-12

### E.47.1. Overview

This release is based on Postgres Pro Standard 9.6.3.1 and PostgreSQL 9.6.3.

Major enhancements over Postgres Pro Standard 9.6.3.1 include:

- Updated the pg_probackup backup manager to version 2.0 that includes the following new features:

  - Saving backups for different databases in a single backup catalog

    Storing backup data in a compressed state to save disk space

    Extended logging settings

- Added distribution for Debian 9.

- Added upstream patches that fix potential data corruption during freeze.

### E.47.2. Migration to Version 9.6.3.2

A dump/restore using pg_dumpall, or use of pg_upgrade, is required for those wishing to migrate data from any previous major release.

A dump/restore is not required for those running 9.6.3.1.

However, if you are upgrading from vanilla PostgreSQL 9.6.x, some catalog changes should be applied.

If you use binary packages, and your database is in the default location, this upgrade should be performed automatically. If you've compiled Postgres Pro from source or create your database in a non-default location, running `initdb` manually, you should run `pgpro_upgrade` script provided in this distribution.

Before running the script, you should stop postgres service. Script should be run on behalf of the user owning the database (typically postgres) and PGDATA environment variable should be set to the directory where database resides.
