* Hash-deduplicated state storage (and migrations) for PostgreSQL and SQLite * Refactor droomserver database setup for migrations * Fix conflict statements * Update migration names * Set a boundary for old to new block/snapshot IDs so we don't rewrite them more than once accidentally * Create sequence if not exists * Fix boundary queries * Fix boundary queries * Use Query * Break out queries a bit * More sequence tweaks * Query parameters are not playing the game * Injection escaping may not work for CREATE SEQUENCE after all * Fix snapshot sequence name * Use boundaried IDs in SQLite too * Use IFNULL for SQLite * Use COALESCE in PostgreSQL * Review comments @Kegsay
