## E.14. Postgres Pro Enterprise 9.6.3.2

Release date: 2017-06-28

### E.14.1. Overview

This release is based on Postgres Pro Enterprise 9.6.3.1.

Major enhancements over Postgres Pro Enterprise 9.6.3.1 include:

- Updated RUM index to version 1.1 (See Section F.54.)

- In Compressed File System (CFS), fixed a bug caused by invalid merge, as well as included many other fixes.

- Improved multimaster extension:

  - Fixed replication issues and other issues caused by running the `mtm.make_table_local` function.

  - Added the `multimaster.major_node` variable. With this variable set to `true` the cluster node can continue working even if connection to the majority of the nodes is lost.

- Fixed an issue with pgpro_scheduler background worker hanging at the scheduled job startup for cases when one of the critical tables is locked.

- Fixed an issue with deleting functions declared in languages that do not have the `validate` method (for example, in `PL/TCL`).

### E.14.2. 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.

Dump/restore is necessary when migrating from PostgreSQL, Postgres Pro Standard, or Postgres Pro Enterprise edition.

For upgrades from previous releases of Postgres Pro Enterprise, Postgres Pro Standard, or 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 created your database in a non-default location, running `initdb` manually, you should run the `pgpro_upgrade` script provided in this distribution.

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