Re-re-re-review and tweak the new-database initialization dns.sql script
and the dns-1.0-1.2.sql upgrade script to ensure the resulting structure
is as close as possible to identical to minimize any possible breakage.

Creating a database with the 1.0 SQL init, then applying the 1.0-1.2
upgrade script, will result in pg_dump output with only one difference;
the setval for the sequence on user_id in the users table. Sematically,
there is no difference in the database behaviour (the first new user
created will have ID 2), but the changes make it easier to copy-paste
pg_dump schema fragments if further updates to the default schema are
required.
