Getting started with PostgreSQL can be both exciting and challenging. It's more than just another database—it's a system packed with features that can change how you handle data. Every Friday, Michael (pgMustard) and I discuss these features on our podcast, Postgres.FM (there is also a video version on YouTube). We've been at it for 55 weeks straight since July 2022, and we're not stopping anytime soon. Our latest episode was all about helping newcomers to PostgreSQL. After seeing the huge ...|
Test environments that are 10x cheaper and 10x faster than RDS clones – compare various ways to clone databases in AWS, including RDS clones, Aurora thin clones, and DLE clones|
The Postgres.ai team is happy to announce the release of version 3.2 of Database Lab Engine (DLE), an open-source tool that provides blazing-fast database cloning and branching for any PostgreSQL database to build powerful development, test, QA, and staging environments. Database Lab Engine is an open-source technology that enables thin cloning for PostgreSQL. Thin clones are exceptionally useful when you need to scale the development process. DLE can manage dozens of independent clones of yo...|
I'm very pleased to announce the very first preview version of Database Lab Engine (DLE) for AWS Marketplace. If you're using AWS, this is the fastest way to have powerful database branching for any database, including RDS and RDS Aurora. But not only RDS: any Postgres and Postgres-compatible database is supported as a source for DLE. Now, for a fixed price (paying just for one EC2 instance and an EBS volume), you can have dozens of DB clones being provisioned in seconds and delivering indepe...|
'rake db:migrate' – a command known to any Ruby developer. But how many times did we step on the same rake? In his article "Lesser Known PostgreSQL Features", @be_haki describes 18 Postgres features many people don't know. I enjoyed that article, and it inspired me to write about "anti-features" – things that everyone should avoid when working in probably the riskiest field of application development – so-called "schema migrations". This is one of my favorite topics in the field of rela...|
The Postgres.ai team is happy to announce the release of version 3.1 of Database Lab Engine (DLE), the most advanced open-source software ever released that empowers development, testing, and troubleshooting environments for fast-growing projects. The use of Database Lab Engine 3.1 provides a competitive advantage to companies via implementing the "Shift-left testing" approach in software development. Database Lab Engine is an open-source technology that enables thin cloning for PostgreSQL. T...|
Recently, I have read a nice post titled "Query Progress Bar", by Brian Davis. It describes an interesting approach to observing the progress of slow query execution. At some point, the author mentions: > Don't use this in prod. And I agree. The article discusses long-running queries such as SELECTs, UPDATEs, DELETEs, and quite "invasive" methods of progress monitoring. In an OLTP production scenario, in most cases, we should try to limit the duration of such queries, setting statement_timeou...|

What is this about? Many DDL statements in PostgreSQL support modified IF EXISTS / IF NOT EXISTS. For example: test=# create table if not exists mytable(); CREATE TABLE test=# drop table if exists mytable; DROP TABLE I recommend using `IF EXISTS` / `IF NOT EXISTS` in DDL only when necessary. Here are three examples that demonstrate how the overuse of these words may lead to negative consequences.|
Based on a true story. This article was originally published in 2018. This is a reviewed and extended version of it. The discussed findings can be applied to any actual major version of PostgreSQL. Primum non nocere "Primum non nocere" – this is a fundamental principle that is well-known to anyone working in healthcare: "first, do no harm". It is a reminder: when considering any action that is supposed to improve something, we always need to look at the global picture to see if there might ...|
The Platform now supports resetting of DLE clones to any data snapshot.|
Now it is possible to dump/restore multiple databases at the same time and use different pg_dump formats and compression formats of plain-text dump. DLE and related products configuration structure was significantly reworked and require manual action to migrate to the new version.|
Is 200 ms slow for an SQL query? What about 20 ms? When do we need to optimize?|
PostgreSQL subtransactions (nested transactions) may cause multiple performance and scalability issues: higher rates of XID growth and higher risks of transaction ID wraparound, performance degradation when more than PGPROC_MAX_CACHED_SUBXIDS (64) are used in a session, drastic performance slowdowns when subtransactions are combined with SELECT .. FOR UPDATE, and finally, brief downtime on standbys when subtranasctions used on the primary in paralell with long-running transactions or just slo...|

Deploying DB schema changes in heavily loaded systems is challenging. In this article, we explore one of the challenges - how to avoid situations when DDLs get blocked, wait to acquire a lock, and during that, start blocking other sessions.| PostgresAI
(Io, a Jupiter's moon) SQL query optimization is challenging for those who have just started working with PostgreSQL. There are many objective reasons for this, such as: the difficulty of the field of system performance in general, lack of good "playground" environments where people can experience how databases work at a larger scale, lack of certain capabilities in Postgres observability tools that are still developing (though, at a good pace), insufficiency of good educational materials. ...| Postgres.AI
