You don't have to understand everything, it is ok. And joining a language community for a language you hate just to rant about it, shows that you should try to focus on letting things go. It feels a bit obsessive.
If you actually like to have a conversation about the language, I suggest you be a bit more specific and we will try to answer to the best of our ability.
Have a nice day, and don't forget to breathe.
Had to test with Kagi also, leads with official documentation, after that tutorials and unofficial things. Nothing obviously irrelevant. The only thing with the Kagi results, was that there were a few very simmilar official documentation links (for different postgresql versions) at top. But, still good search results. Not sure why anyone is still using google, when there are quite a few better alternatives availale
