No, I don't recall.  It might be worth digging in the archives.

Well, mumble.  I guess the question is what are the triggers going to
*do*?  If they are going to cross-check against tables that may not be
restored yet, then you have a problem if you don't turn them off.  OTOH
it's easy to imagine that this may allow you to load inconsistent data.
'Tis a puzzlement.

For now, I'd be happy if the normal case of a simple restore doesn't
generate warnings.  Improving on that probably takes more thought and
risk than we should be putting in at the end of beta.
