Taking a look at the current ./src/bin/scripts executables, I see only
2 out of 9 (`dropdb` and `dropuser`) which have "-i" mean
"--interactive", and `reindexdb` has another meaning for "-i"
entirely. So I'm not sure there's such a clear precedent for having
"-i" mean "--interactive" within our scripts, at least.

I think breaking backwards compatibility probably won't fly (and
should probably be handled by another patch, anyway). I guess it's OK
to keep the patch's current behavior, given we are already
inconsistent about what "-i" means.

OK.
