bun run main.ts

Setup

If not already done, add the following trigger to the database:

CREATE OR REPLACE FUNCTION cron_update()
  RETURNS TRIGGER AS $$
DECLARE
BEGIN
  PERFORM pg_notify('cron_update', TG_OP);
  RETURN NEW;
END;
$$ LANGUAGE plpgsql;

CREATE TRIGGER "cron_update"
  AFTER INSERT OR DELETE OR UPDATE OF value, deleted_at ON crons
  EXECUTE PROCEDURE cron_update();

This will notify the cron_update channel whenever a row is inserted, updated or deleted in the crons table and allow the scheduler to update its internal state.
