The area of focus for the first release is backup performance, ease of use, partitioning enhancement and scalability.  The goal is continue to develop on a very strong base and provide tremendous value to our end-users in variety of areas.

PostgreSQL 12 comes with a number of excellent and exciting features, it continues to improve the existing partitioning functionality by adding fast partition pruning along with additional partitioning improvements. It also contains a number of general performance improvements, optimisations for b-tree and other indexes, automatic inlining of common table expression (CTE). There are number of new authentication features including (Encryption of TCP/IP connections when using GSSAPI authentication), support for SQL/JSON path language and number of other exciting features.

The product license which is also available on the highgo ca website (https://yum.highgo.ca) is very flexible to allow end-users to use the product for commercial or non-commercial use without getting any authorisation from Highgo Software.

Key Features in HG-PGSQL 1.1

HighGo Postgres Server 1.1 is built on top of PostgreSQL 12.1 and provides the following key features :

Enhanced Partitioning Syntax

Enhancing the table partitioning syntax to allow specifying the parent table and partitions in the same SQL statement. This is a ease of use feature that will take away the hassle of creating partitions separately from the parent table. This will allow the end-user to specify the partitions and sub-partitions using the native PostgreSQL syntax in the same statement as the parent table.

This feature is particularly useful when the end-user is creating large table that comprised of partitions and sub-partitions. This syntax will also simplify when migrating database schema other RDBMS to PostgreSQL since the combined syntax is support by most RDBMS 

solutions.

Please refer to the comprehensive user guide (link given above) for details on the feature and examples.

Shard Management

Provide the capability of creating an sharded table by specifying parent table and foreign partitions in the same statement. This feature adds the ability to push-down partitions to the foreign server, it is part of the horizontal scalability / sharding effort. The user can specify the partitions along with the foreign server (shards) and using the push-down clause the partitions will be automatically created on the foreign servers. This is really exciting feature that automates the creation of partitions on the shards. This capability is added to postgres_fdw in this release, it can be extended to other databases.

This feature is very useful as it will automatically create the partitions and sub-partitions tables on the foreign servers. When the user drops the parent table, the user has the option to automatically removed the foreign partitions.

The complete syntax for shard management is part of the comprehensive user guide.

Parallel Base Backup

Greatly improve the performance of full base backup by adding parallelism to the backup operation. This feature is adding parallelism to base backup by spawning a configurable number of parallel workers for performing the backup. The parallel backup feature enables the user to use more system resources by spawning multiple workers for taking backup. The parallel backup feature benchmarking was done using AWS instances, benchmarking results and details were released are part of the white paper available on the products page. The link for the white-paper is also in the introduction section of the blog.

The parallel backup feature is still undergoing some discussion and changes in the community. The target is to get this feature committed for PG-13 and have the latest version of parallel backup as part of a minor release of HG-PGSQL.
