Yeah, and then an application comes in and wants to write more than

hmm, i dont think, its really needed. if you really want to do that,
you should also think _very carefully_ 'bout what you're doing.
and so you can type the 3 more statements to create a new table,
copy the data, drop the old table and rename the new one.
