| Riak, a scalable and reliable data store, is available in Fedora 15.
| |
| | |
| Riak is a Dynamo-inspired key/value store, written in Erlang, that scales predictably and easily. Riak also simplifies development by giving developers the ability to quickly prototype, test, and deploy their applications.
| |
|
| |
|
| A truly fault-tolerant system, Riak has no single point of failure. No machines are special or central in Riak, so developers and operations professionals can decide exactly how fault-tolerant they want and need their applications to be.

| |
| * Easier database object permissions management
| |
| * Broadly enhanced stored procedure support
| |
| * More advanced reporting queries
| |
| * New trigger features
| |
| * Deferrable unique constraints
| |
| * Mass updates to unique keys are now possible without trickery
| |
| * Exclusion constraints
| |
| * New and enhanced security features
| |
| * New high-performance implementation of the LISTEN/NOTIFY feature
| |
| * New implementation of VACUUM FULL
| |
| * Multiple performance enhancements for specific types of queries, including elimination of unnecessary joins
| |
| * EXPLAIN enhancements
| |
| * hstore improvements
| |
| | |
| In addition, there is a new contrib module pg_upgrade to support in-place upgrades from 8.4 to 9.0. This means that you can upgrade from a Fedora 12 or later database without a database dump and restore. To do that, install the postgresql-upgrade package and run '''service postgresql upgrade''' as root. It's advisable to have a separate backup in case of trouble, but the actual database conversion requires only a few minutes with this approach.

PostgreSQL 9.4.1
In Fedora 22, the postgresql packages have been updated to the upstream version 9.4.1, which provides various bug fixes and enhancements described on upstream 9.4.0 release notes and 9.4.1 release notes pages.
Migration to new PostgreSQL version may be done by running of the post-upgrade script postgresql-setup (meaning that you may firstly update your Fedora installation from version 21 to 22 and then perform database stack update). Users are encouraged to do full database dump (for backup purposes) before Fedora upgrade to 22. For more info about migration look into the README.rpm-dist file distributed in postgresql package.
