Release date: 2017-05-15

### E.48.1. Overview

This release is based on Postgres Pro Standard 9.6.2.1 and PostgreSQL 9.6.3.

- Fixed WAL inconsistency bug in covering indexes.

- Added distribution for SUSE Linux Enterprise Server 12 SP1 and Ubuntu 17.04.

- Applied patches to optimize inheritance.

- Updated PTRACK patch to version 1.2.

- Provided performance improvements for queries typical for 1C solutions.

### E.48.2. Migration to Version 9.6.3.1

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 9.6.2.1.

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.
