-- Declare the columns that are NOT NULL on SQLite as NOT NULL too, so an export from either database can be imported into the other
-- The application never writes NULL into these columns, but backfill any NULL left over from older versions first
-- Empty strings are what the application writes for these values and what readers of kv treat as missing
