  • | 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!

     

  • | 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.

  • | 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.

  • | 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.

  • | 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.

  • | 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.

  • 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.

Postgres Extensions

  • JIT compilation of queries

    Current approach for execution is essentially a kind plan tree interpretation. JIT-compilation of queries means compilation of plan tree into binary. Such compilation could get rid of multiple levels of indirection therefore accelerating queries.

  • Pluggable storages

    We achieved a significant progress in PostgreSQL extendability: FDWs, custom access methods, generic WAL. And we’re not so far from having pluggable storage engines. Concept of API was presented at PGCon 2016.

  • 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.
