What commenters say

• Using language models like ChatGPT to generate SQL queries can be helpful, but it's also important to understand the underlying database schema and query optimization techniques.
• Dumping a database schema into a language model can potentially expose sensitive information, such as intellectual property.
• Railroad diagrams can be a useful tool for understanding complex syntax, but they can also be confusing and out of sync with the actual syntax-parsing code.
• Writing SQL queries with keywords in all caps is not necessary, but it can improve legibility and visual pattern matching.
• Some commenters disagree on the usefulness of language models for generating SQL queries, with some finding them helpful and others preferring to write queries manually.
• The importance of understanding how Postgres works and how to optimize queries is a key takeaway from the article and the comments.
• Using tools like Jetbrains' language injection feature can improve syntax highlighting and validation for embedded SQL strings in programming languages like PHP.
• There are different opinions on the best way to learn and work with Postgres, with some preferring to learn through hands-on experience and others relying on documentation and tutorials.
