March 12 | PGConf.Online 2021 wrap-up: 57 talks, 30 international speakers, 2000+ registrants!

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!

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.

February 3 | Postgres Professional at FOSDEM 2021

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.

July 28 | Locks in PostgreSQL: 4. Locks in memory

To remind you, we've already talked about relation-level locks, row-level locks, locks on other objects (including predicate locks) and interrelationships of different types of locks.

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.

July 15 | Locks in PostgreSQL: 3. Other locks

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.

July 1 | Locks in PostgreSQL: 2. Row-level 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.

pg_variables

Functions for defining and using variables in client sessions.

mamonsu

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

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.

Connection pooling

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.

Better temporary tables

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.

Backup

We work on several backup problems: block-level incremental backup, backup validation, partial backup/restore.
