Personnally, i do this:
alter table xxx rename bad_col to ___scratchY;
where Y is a number.
Every day, just before the vacuum is done, a cron
will stop the daemon and make the operation being
proposed below, if ___scratchYs fields are found.
I suspect databases like SQL Server7
to announce delete row possible, but to content
themselves with renaming and hiding.
