## E.3. Postgres Pro Enterprise 10.5.1

Release date: 2018-09-03

### E.3.1. Overview

This release is based on Postgres Pro Standard 10.5.1 and Postgres Pro Enterprise 10.4.1. All changes inherited from Postgres Pro Standard 10.5.1 are listed in Postgres Pro Standard 10.5.1 Release Notes. As compared with Postgres Pro Enterprise 10.4.1, this version provides the following changes:

- Log files now include the number of rows and the size of the data passed to the client if `log_duration` is enabled or if the query runs longer than `log_min_duration_statement`.

- You can allow the primary server to continue running even if some of its synchronous standbys are disconnected or lag behind for more than the specified threshold. This can result in shorter downtime of the primary when using synchronous replication. For details, see synchronous_standby_names and synchronous_standby_gap.

- Updated pg_pathman module to version 1.4.13. For a full list of changes, see pg_pathman Wiki.

- Updated multimaster module.

- Updated in_memory module.

- Updated vops module.

- Miscellaneous bug fixes.

### E.3.2. Migration to Version 10.5.1

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.
