Kaarel Moppel: Best pg_dump compression settings for Postgres in 2024

Neues vom PostgreSQL Planet - 4. Januar 2024 - 23:00
Time between Christmas and New Year is always a good quiet time to be able to concentrate and tick off some mouldy TODO list items. For me this time the top item was a script (which turned into a small framework somehow), to download and import some openly available “real...

I waited for a couple of days to start my PG Day Chicago marketing campaign, and I hope that by now, everybody is more or less back to office/back to work/back to reality. Right? So, here is my list of aska:

Robert Haas: Incremental Backup: What To Copy?

Neues vom PostgreSQL Planet - 3. Januar 2024 - 18:28

Five days before Christmas I committed my patch to add incremental backup to PostgreSQL. Actually, I've been committing preparatory patches for some months now, but December 20 saw the two main patches land. Since then, there's been a bunch of bug-fix commits, and there are still a few pending items that need to be addressed, but the core of the feature is now committed. If you want a quick overview of the feature, Lukas Fittl has a great video about that.

semab tariq: AI Meets PostgreSQL – The pgvector Revolution in Text Search

Neues vom PostgreSQL Planet - 3. Januar 2024 - 8:50

For decades, PostgreSQL has reigned as the relational database champion, meticulously organizing data into rows and columns. But the information age craves more than just order; it demands understanding. Enter pgvector, a revolutionary extension that infuses PostgreSQL with the magic of vector data. Imagine text, images, or even sounds transformed into multi-dimensional points in space, […]

Peter Eisentraut: Using clangd for PostgreSQL development

Neues vom PostgreSQL Planet - 3. Januar 2024 - 6:00

I have started using clangd (with a “d”) for PostgreSQL development. Maybe you want to try it too.

Introduction

What is clangd? To quote directly from the web site:

clangd understands your C++ code and adds smart features to your editor: code completion, compile errors, go-to-definition and more.

clangd is a language server that can work with many editors via a plugin.

(They talk about C++, but this applies to C equally.)

Adam Johnson: PostgreSQL: Full text search with the “websearch” syntax

Neues vom PostgreSQL Planet - 3. Januar 2024 - 1:00

PostgreSQL’s powerful full text search feature supports several query syntaxes. Of these, a website search feature should typically pick the websearch syntax. websearch copies some features from popular search engines, as covered below, offering familiar short syntax to users. It is also forgiving and will never raise a syntax error for user input, whilst other syntaxes can.

Elizabeth Garrett Christensen: Postgres TOAST: The Greatest Thing Since Sliced Bread?

Neues vom PostgreSQL Planet - 2. Januar 2024 - 14:00

If you’ve ever dug under the hood of Postgres a bit, you’ve probably heard about the page. This is the on-disk storage mechanism and it's limited to an 8kb size. But what happens when you have data bigger than that 8kb? TOAST is made. Postgres TOASTs data by splitting it up into smaller chunks. TOAST stands for The Oversized Attribute Storage Technique.

TOAST happens automatically, you don’t set up anything, it just comes with Postgres out of the box. So why should you care?

Jonathan Katz: Thoughts on PostgreSQL in 2024

Neues vom PostgreSQL Planet - 2. Januar 2024 - 1:00

A question I often hear, and also ask myself, is “where is PostgreSQL going?” This is a deep question: it’s not limited to the work on the core database engine, but rather everything going on in the community, including related open source projects and event and community development. Even with the popularity of PostgreSQL, which was selected as DB Engine’s “DBMS of the Year” for the fourth time, it’s a good idea to step back at times and reflect on what PostgreSQL will look like in the future.

  • rewriting dbms_pipe and dbms_alert in orafce. Now the conditions variables are used (for synchronization)  instead timeouts, and the lags in the communication are significantly reduced,
  • fix pspg and PDCursesMod so pspg can be used with other curses than ncurses. Originally pdcurses didn't support stream redirection. Still only VT environment is supported (far target is support pspg on new Microsoft Windows terminal),
  • Rewriting background of profiler, tracer routines in plpgsql_check.

Shayon Mukherjee: Introducing pg_easy_replicate 2.0

Neues vom PostgreSQL Planet - 29. Dezember 2023 - 17:53
It’s exciting to share that pg_easy_replicate, a project I’ve been maintaining, has hit a new milestone with its 2.0 release! This tool is more than a practical solution for setting up logical replication between PostgreSQL databases—it’s been a profound source of learning about PostgreSQL concepts for me. Engaging with the community and discovering the ways they use pg_easy_replicate has been equally satisfying, making this journey an enjoyable and insightful experience.

Jobin Augustine: Human Factors Behind Incidents: Why Settings Like “idle_session_timeout” Can Be a Bad Idea

PostgreSQL 14 introduced the parameter [crayon-6596e09a7a5de463948439-i/], and, unfortunately, many DBAs jumped to start using it without understanding or by ignoring the consequences. In a short span of time, it has become one of the most misused parameters in many PostgreSQL installations. There is nothing wrong with [crayon-6596e09a7a5e7580417234-i/]  from a technical perspective; even without this parameter, […]

Hubert 'depesz' Lubaczewski: Proper support for I/O Timings on explain.depesz.com

Neues vom PostgreSQL Planet - 29. Dezember 2023 - 13:20
Very long time ago (in PostgreSQL 9.2) we got ability to get, from EXPLAIN, information how long Pg spent on I/O operations. Reads and writes. Over the years situation has changed. Originally it looked like this: I/O Timings: read=15.792 write=26.804 This told us that Pg spend 15.8ms reading from disk, and 26.8ms writing.

Dmitry Dolgov: Demand the impossible: rigorous database benchmarking

Neues vom PostgreSQL Planet - 29. Dezember 2023 - 1:00
Everyone knows benchmarking is hard (and writing about benchmarking is double as hard), but have you ever asked 'why'? There could be at least few reasons, and they usually have something to do with the inherent duality: it's necessary to combine expertise from both the domain specific area and general analytics expertise; one have to take into account both known and unknown factors. In this article we try to use this as a base to answer the following: how to not blow up your PostgreSQL benchmark?
