Re: Two sequences associated with one identity column

Again as I wrote above, drop identity complains about more than one sequence.

I have no idea how this customer arrived at this situation or if it
affects other environments (this is actually a dev database that we're
trying to upgrade as the first step in an upgrade project).

I suspect the dump will just show two sequences that need to be
imported and it will fail on the second one. I'll make a dump.
