Okay, I changed only is_no_vacuum in this patch and other similar variables would be changed in another patch. > >>> I think that the "-I" it should be added to the "--help" line, as it is >>> done >>> with other short & long options. >> >> >> Okay, I'll leave it as of now.

So we don't need to have a command as a option for other initializatoin commands. Attached latest patch. Please review it.
