FYI, it was proposed here:

dropdb and dropuser both support a similar option named --if-exists. I
suggest --if-exists instead of --conditional-drops for consistency.
I've only glanced at the patch, but if it makes no sense to use
--conditional-drops (or --if-exists, whatever it ends up being called)
without --clean, then attempting to do so should raise an error.
