What should I do if I *know* there will be a FK failure but I want to correct
it manually. Perhaps by creating all the necessary target records, perhaps by
deleting or updating the dead references. Perhaps with a mix of these.
As it stands I have to delete the FK constraint, load the table, and fix the
data. Then recreate the FK constraint -- with the danger that I'll get the
definition wrong -- and wait for the constraint to be verified.
If I could disable and reenable the constraint the danger that I would get the
definition wrong would be eliminated. And if I had already done the work to
ensure there were no broken relationships I would optionally be able to skip
the redundant automatic check. I could even have done the verification myself
while the data wasn't live for example.
The database is a tool. It's annoying to have a tool that tries to outsmart
the user.
