This is my experience as well, I spent a few years complaining that my colleagues didn't know their database well enough, and it was causing unnecessary bugs and poor performance. I wanted the company to pay for some basic courses on the databases we were using, especially for the more junior Devs. Instead we switched database like 11 times and now I don't know the database either. The bugs and poor performance lingers though.
