Well, that -- SQL keywords in uppercase -- does tend to highlight the table & column names in lowercase excellently. When everything is in lowercase, a query requires too much effort to pick out its purpose.

Needless to say all uppercase is even harder to parse; doable but I would rather do 0,$s/./\L&/g if only to make reading easier.
