-- Reverses migration 0022. Drop tables in reverse dependency order.
-- This will fail if any rows in audit_log or user_invites reference
-- users that were deleted with ON DELETE SET NULL semantics; those
-- references will already be NULL so the drops should succeed cleanly.

DROP TABLE IF EXISTS audit_log;
DROP TABLE IF EXISTS user_invites;
