## E.2. Postgres Pro Enterprise 10.5.2

Release date: 2018-09-17

### E.2.1. Overview

This release is based on Postgres Pro Standard 10.5.2 and Postgres Pro Enterprise 10.5.1. All changes inherited from Postgres Pro Standard 10.5.2 are listed in Postgres Pro Standard 10.5.2 Release Notes. As compared with Postgres Pro Enterprise 10.5.1, this version also provides the following changes in `pgbench`:

- `pgbench` now supports compound commands.

- You can now limit the time allotted for transaction retries using the `--latency-limit` option. If this option is used together with `--max-tries` set to zero, transactions can be retried as many times as `--latency-limit` permits.

- The reported TPS and the number of processed transactions now exclude skipped and failed transactions.

### E.2.2. Migration to Version 10.5.2

If you are upgrading from a Postgres Pro Enterprise version based on the same PostgreSQL major release, it is enough to install the new version into your current installation directory.

### Important

When upgrading from versions 10.3.3 or lower, you must execute the `REINDEX` command for GiST and SP-GiST indexes, as well as indexes that use `mchar` or `mvarchar` types.

To migrate from PostgreSQL, Postgres Pro Standard, or Postgres Pro Enterprise versions based on any previous PostgreSQL major release, see the instructions in Postgres Pro Enterprise 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 collation provider for the migrated database.
