Sorry if there was any confusion caused, it was not my intention to mislead any users. I'll update the post with a (hopefully clearer) name. Perhaps "PostgreSQL training courses"?

Quick (and quite possibly ignorant) question though: what's the difference between a "training course" and what's listed there though? Seems like the content in the course linked covers views, functions, etc. which is content which I could see a Postgres developer using regularly

Sorry to hear that you feel that the title is misleading. It was definitely not my intention to mislead - the MySQL For Developers thread had some great content and I thought that PostgresPro's content would be a useful Postgres centered complement to what was posted. I'd looked through PostgresPro training material in the past and thought that there were useful snippets in the courses mentioned in the link above.

Could you tell me more about what you felt was misleading, and what you were expecting instead? If you have a preferred title in mind for this post I'm happy to try and change that too.

I believe both the Introduction to PostgreSQL and DEV1: Basic Server-Side Application Development courses are free. You can find the corresponding YouTube lectures by clicking on the respective links.

Disclaimer: I didn't make either course, just chanced upon them a while back
