Do I get that right: the only reason to do
max(sysid) or a user-supplied ID in CreateUser() (commands/user.c) is
that
we don't have the ability to get sequences over the *.BKI/initdb
mechanism?
If that is true and you think it's possible and worth to have sequences
in the bootstrap,
I volunteer to do this.

I think it's much better to leave this to somebody with far more
understanding of the subject.
