Hi. Good to see a familiar face from the zope.org list here.
What version of PG are you using? I remember problems with foreign key
dependencies, but it's been a while since I've seen it happen.
If you use pg_dumpall, you'll get the statements to recreate users (&
groups, etc.). `pg_dumpall -g` will give you just this information, if
you've dumped the databases separately.
Of course, one solution would be a sed/perl/python/whatever script to easily
pull the constraints to the end, but first let us know what PG ver this is.
