Was wondering about it, too -- intuitively I 'd like to say, "stop all
indexing" until the column is added, then say "reindex", is it
doable? Or would it take longer anyways? SInce I don't index on that
new column, I'd assume my old indices would do -- do they change
because of rows deletions/insertions, with the effective new rows
addresses?
