 CloudSync verifies the tenant database connection before registration is persisted. If verification fails, the database is not registered.
 
 For SQLite Cloud databases, `databaseName` identifies the target database and CloudSync switches to it when running CloudSync operations. For Postgres databases, the `connectionString` must point to the target database.
