Replace dollar-quoted strings with simple single-quoted strings in cron.schedule() function calls. The cron.schedule() function expects text literals, not dollar-quoted blocks. Use quote_literal() for the interval value in the cleanup query to properly escape the string.

-- Migration: Extend scheduled_notifications for 9 push notification reminder types
|
|
-- Adds support for task-based, ISR-based, and pass-slip-based notifications alongside existing shift reminders.
|
|
-- Creates modular enqueue functions for each notification type, called by a master dispatcher.
|
|
-- Uses pg_cron + pg_net to fully automate enqueue and processing without external cron.

|
|
ALTER TABLE public.scheduled_notifications
