You stated: Why small companies get talked into running MSQL or Oracle or MySQL is beyond me. And even if (and that's a big IF) they needed more "power", there's Postgres. I'm explaining you that SQLite has big, very real limitations that any of those alternatives are a good workaround for. And as for Postgres, that's just one more argument never to use SQLite. So how can it be "underestimated"? SQLite make sense in one single situation: if you absolutely need an embedded database. A corporate blog is not one of them. SQLite isn't used much because it's limited compared to the alternatives.
