## E.53. Postgres Pro 9.5.14.1

Release date: 2018-08-14

### E.53.1. Overview

This release is based on PostgreSQL 9.5.14 and Postgres Pro Standard 9.5.13.1. All improvements inherited from PostgreSQL 9.5.14 are listed in PostgreSQL 9.5.14 Release Notes.

Major enhancements over Postgres Pro Standard 9.5.13.1 include:

- The `pg_variables` module now supports transactional variables. (See Section F.51.)

- The `auto_explain` can now display planning time.

- Postgres Pro Standard version for Windows has been improved:

  - Lifted an implicit restriction on the number of simultaneously open files for each server subprocess.

### E.53.2. Migration to Version 9.5.14.1

Depending on your current installation, the upgrade procedure will differ.

If you are running Postgres Pro 9.5.13.1, it is enough to install the 9.5.14.1 version into the same directory. For earlier Postgres Pro versions, `pgpro_upgrade` script is required to complete the upgrade:

- If you are upgrading your installation from a binary package, and your database is in the default location, `pgpro_upgrade` is run automatically, unless you are prompted to run it manually.

- If you compiled Postgres Pro from source code or created your database in a non-default location, you must run `pgpro_upgrade` script manually.

### Important

Before launching `pgpro_upgrade` manually, you must stop the `postgres` service. The script must be run on behalf of the user owning the database (typically postgres). Running `pgpro_upgrade` as root will result in an error.

To migrate to this version from vanilla PostgreSQL, perform a dump/restore using pg_dumpall.
