PostgreSQL releases PostgreSQL 15

The team behind the open-source database PostgreSQL today announced the release of PostgreSQL 15.

According to the project maintainers, this release builds on the performance improvements of recent releases with gains for managing workloads in both local and distributed deployments, including improved sorting.

PostgreSQL 15 is intended to improve the overall developer experience with the addition of the MERGE command for writing conditional SQL statements that can include INSERT, UPDATE, and DELETE actions within one statement as well as several capabilities for observing the state of the database.

“The PostgreSQL developer community continues to build features that simplify running high performance data workloads while improving the developer experience,” said Jonathan Katz, a PostgreSQL core team member. “PostgreSQL 15 highlights how, through open software development, we can deliver to our users a database that is great for application development and safe for their critical data.”

This latest release improves on PostgreSQL’s in-memory and on-disk sorting algorithms, with benchmarks showing speedups of 25% – 400% depending on which data types are sorted.

Additionally, Using row_number(), rank(), dense_rank(), and count() as window functions also bring performance benefits in PostgreSQL 15.

This release also provides heightened flexibility for managing logical replication with row filtering and column lists. These features allow users to choose to replicate a subset of data from a table.

It also introduces a new logging format: jsonlog which outputs log data using a defined JSON structure, allowing PostgreSQL logs to be processed in structured logging systems.

Difference between Web Designer and Web Developer Neeraj Mishra The Crazy Programmer

Have you ever wondered about the distinctions between web developers’ and web designers’ duties and obligations? You’re not alone! Many people have trouble distinguishing between these two. Although they collaborate to publish new websites on the internet, web developers and web designers play very different roles. To put these job possibilities into perspective, consider the construction of a house. To create a vision for the house, including the visual components, the space planning and layout, the materials, and the overall appearance and sense of the space, you need an architect. That said, to translate an idea into a building, you need construction professionals to take those architectural drawings and put them into practice. Image Source In a similar vein, web development and design work together to create websites. Let’s examine the major responsibilities and distinctions between web developers and web designers. Let’s get going, shall we? What Does a Web Designer Do?

2022: The year of hybrid work

Remote work was once considered a luxury to many, but in 2020, it became a necessity for a large portion of the workforce, as the scary and unknown COVID-19 virus sickened and even took the lives of so many people around the world.  Some workers were able to thrive in a remote setting, while others felt isolated and struggled to keep up a balance between their work and home lives. Last year saw the availability of life-saving vaccines, so companies were able to start having the conversation about what to do next. Should they keep everyone remote? Should they go back to working in the office full time? Or should they do something in between? Enter hybrid work, which offers a mix of the two. A Fall 2021 study conducted by Google revealed that over 75% of survey respondents expect hybrid work to become a standard practice within their organization within the next three years.  Thus, two years after the world abruptly shifted to widespread adoption of remote work, we are declaring 20
