PostgreSQL and even things like SQLite are fantastic tools for programmers with time to invest in learning them an their quirks. What a modern database could do that they can't is be comprehensible to a power-user. Modelling and querying data could be far simpler than SQL makes it. A modern database language/interface would be far more useful to most than general purpose programming languages are. We can do better for end-users than forcing them to grapple with archaic `SELECT` statements. The crowd that have invested in learning the language already will disagree, of course, but far too many newbies self-select out of that group because it seems too complicated to them. It doesn't have to be so.
