Design and development of mission-critical high-performance systems based on PostgreSQL
PGConf.Online wrapped up 10 days ago, and we want to share some important stats with you. We were glad to have welcomed 2000+ registrants this year with 700-900 of them joining us online each day! The total attendance/registration rate for all three days was near 75%, which is amazing!
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!
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.
It’s this time of the year again, and FOSDEM is coming! In 2021, Postgres Professional is really well-represented in the PostgreSQL devroom, as we have 5 talks accepted by the Committee. Let’s take a look at all presentations to be given by our team at this conference.
The following discussion of locks in RAM finishes this series of articles. We will consider spinlocks, lightweight locks and buffer pins, as well as events monitoring tools and sampling.
We've already discussed some object-level locks (specifically, relation-level locks), as well as row-level locks with their connection to object-level locks and also explored wait queues, which are not always fair.
We have a hodgepodge this time. We'll start with deadlocks (actually, I planned to discuss them last time, but that article was excessively long in itself), then briefly review object-level locks left and finally discuss predicate locks.
Last time, we discussed object-level locks and in particular relation-level locks. In this article, we will see how row-level locks are organized in PostgreSQL and how they are used together with object-level locks. We will also talk of wait queues and of those who jumps the queue.
Functions for defining and using variables in client sessions.
An active monitoring agent for Postgres Pro. Based on zabbix, mamonsu provides an extensible cross-platform solution that can collect and visualize multiple Postgres Pro and system metrics.
Pg_probackup is a utility to manage backup and recovery of PostgreSQL database clusters. It is designed to perform periodic backups of the PostgreSQL instance that enable you to restore the server in case of a failure.
Working with large number of simultaneous connections almost inevitably leads to usage of connection pools. Unfortunately, present pooling solutions are very limited in access to all PostgreSQL features.
Temporary tables are often being used. Their performance could be increased if they are removed from system catalog. Also it is attractive to allow using temporary tables on read-only standbys.
We work on several backup problems: block-level incremental backup, backup validation, partial backup/restore.
Postgres Professional is the Russian PostgreSQL company founded by Russian PostgreSQL contributors. Company has 50+ employees, among them three Major PostgreSQL Contributors.
Postgres Professional is an active member of international PostgreSQL community, developers had committed 93 patches to the latest release of PostgreSQL 10.0.
Our company had successfully performed large PostgreSQL projects including database migration projects for well-known Russian and international companies. We provide industrial PostgreSQL services: vendor technical support, migration, custom extensions and core patches development, migration-related consulting, training and certification.
