March 8 | Celebrating Women Who Code in Postgres Pro

In early March, before International Women’s Day, we asked our female tech professionals a few questions and were surprised by some of them providing us answers :) Let’s celebrate women who code working here at Postgres Pro and have a look at what they are up to!

February 18 | Postgres Professional is now sponsoring Psycopg development!

Postgres Professional has become one of the main sponsors backing the development of the Psycopg library, the most popular PostgreSQL adapter for the Python programming language.

October 11 | High availability and disaster recovery (HA/DR) for Postgres databases

This is a summary of Postgres Professional’s more than 6 years field experience of providing HA/DR solutions to our customers and it covers both PostgreSQL and Postgres Pro databases.

While most of our customers are making progress on their journeys to the cloud, many of the HA/DR solutions they use from the on-premises world can be used in the cloud as well.

September 27 | А deep dive into PostgreSQL query optimizations

During PostgreSQL maintenance, resource-consuming queries occur inevitably. Therefore, it's vital for every Database Engineer, DBA, or Software Developer to detect and fix them as soon as possible. In this article, we'll list various extensions and monitoring tools used to collect information about queries and display them in a human-readable way.

Then we will cover typical query writing mistakes and explain how to correct them. We will also consider cases where extended statistics are used for more accurate row count estimates. Finally, you will see an example of how PostgreSQL planner excludes redundant filter clauses during its work.

September 8 | Optimizing PostgreSQL queries: questions and answers

During our webinar on PostgreSQL query optimization, we found many of your questions interesting and helpful to the public, if properly answered. Get more useful links and working expert advice from Peter Petrov, our Database Engineer.

pg_variables

Functions for defining and using variables in client sessions.

pg_pathman

The pg_pathman module provides optimized partitioning mechanism and functions to manage partitions.

Effective table partitioning

pg_pathman extension had been developed by Postgres Professional several years ago. It provides the most effective way to partition tables in a database, capable of having thousands of partitions per table. Later a similar partitioning functionality had appeared in community PostgreSQL, being easier in administration, but remarkably less effective. Now we are working on the unification of both partitioning engines.

Page-level data compression

PGLZ compression of individual values is used now in PostgreSQL. That’s good, but sometimes it’s possible to achieve significant compression only when compressing multiple values together. This is why we’re considering page-level data compression.

Multi-master cluster with sharding

Multi-master cluster with sharding which provides read/write scalability as well as high availability is obviously one of most wanted DBMS features. Experience shows that we should move in step-by-step manner in order to have it in core one day. Postgres Professional company joins community efforts in this direction.
