The first appsettings migrations insert the default rows with fixed ids, which a PostgreSQL id sequence does not see; the login lockout migration, the first to insert without an id, then collided with id 1. It now moves the sequence past the existing rows first (a no-op on sqlite), which also covers a database upgraded from any earlier migration. A test compute password exceeded its 14-character column, which only PostgreSQL enforces.
