First beta for PostgreSQL 15 now available

The team at PostgreSQL, a data warehouse for web, mobile, geospatial, and analytics applications, today announced that the first beta release of PostgreSQL 15 is now available for download.

The beta version brings users previews of all of the features that are set to become available when PostgreSQL 15 is made generally available. Information about these features and changes can be found in the release notes. 

According to the company, this release offers several new capabilities for simplifying and enhancing the experience of developers. Included in these features is the introduction of Merge, a SQL standard command for conditionally performing write operations on data.

Before this release, the same behavior could be fulfilled using either stored procedures or with “INSERT… ON CONFLICT”. Developers can now write simple queries to choose the correct data modification action. 

PostgreSQL 15 also builds on existing support for the SQL/JSON path language by adding more standard SQL/JSON functions. Included in these are SQL/JSON constructors, query/introspection functions, and the ability to convert JSON data into a table.

Additionally, the beta release adds more regular expression functions, including regexp_count, regexp_like, and regexp_substr. The range_agg function was also introduced in PostgreSQL 15 and now supports aggregating multirange types.  

This release also offers users significant speedup for sorting data when sorting over larger data sets. 

Performance gains included in PostgreSQL 15 extend to a variety of query types, including the introduction of parallelization for SELECT DISTINCT statements and improvements in performance window functions that use “row_number ()”, “rank ()”, and “count ()”. 

The company strongly encourages interested users to test these new features on their systems and provide feedback in order to eliminate any bugs or issues that may exist. For more information, visit the website.

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?...
