Postgres Pro Enterprise has been updated and open sourced. The new release of the private fork of PostgreSQL is based on PostgreSQL 13.3.

Postgres Pro Enterprise consists of PostgreSQL with some additional patches applied and extensions added, including third-party patches that the PostgreSQL community intends to add to upcoming PostgreSQL versions. The company has also open sourced its multi-master cluster, making these capabilities available to the community.

PostgreSQL 13 was released last year with improvements to its indexing and lookup system that benefit large databases, including space savings and performance gains for indexes, faster response times for queries that use aggregates or partitions, and better query planning when using enhanced statistics. The new release also added parallelized vacuuming and incremental sorting. 

The main improvements in Postgres Pro Enterprise 13 start with online upgrades for minor releases, so users can avoid having to restart their server or interrupting client connections when installing an upgrade. 

There's also an improved compressed file system based on the lz4 compression library, and a more transparent and manageable Write-Ahead Log (WAL).

Other improved features are support for data compression at the database block level to minimize the data footprint and increase performance; and Incremental backup with consistency checks for increased data protection and simplicity, even with terabytes of data.

There's a new built-in task scheduler for delayed, scheduled or asynchronous execution of offline jobs, and table partitioning can now be carried out for more than 10,000 partitions for simpler management and faster processing of large volumes of data in a single database.

One interesting addition is machine-learning based adaptive query planning, which the developers say provides increased adaptability to particular workload and data value distribution.

Postgres Pro Enterprise 13 is available now as a virtual machine image in the Microsoft Azure Marketplace.
