What commenters say

• The new release of PostgreSQL 17 offers significant improvements and features that will enhance the data management experience for users.
• Some users prefer to use cloud-hosted databases, such as Azure SQL, due to their perceived reliability and support, despite the potential for higher costs.
• Others argue that open-source databases like PostgreSQL can be just as reliable and offer more flexibility, but may require more expertise to manage.
• The use of foreign data wrappers (FDW) can be a useful tool for managing data across different databases and platforms.
• Some users have developed their own libraries and tools to work with JSON data in PostgreSQL and other databases, highlighting the need for more standardized solutions.
• The choice between different database management systems, such as PostgreSQL, MySQL, and Azure SQL, depends on specific use cases and requirements.
• The cost of database licenses and hosting can be a significant factor in the decision-making process, with some options being more expensive than others.
• The importance of business intelligence (BI) tools, such as Power BI, is debated, with some arguing that they offer powerful features and others seeing them as overhyped or too closely tied to specific platforms.
