Hi,
I have pg_cron installed. It's working fine for simple schedules but having difficulty scheduling a job to run only on the 4th Sunday of the month at 3 am. It seams to ignore the combination of "day of month" and "day of week". It runs everyday from the 22nd through the 28th. I have tried with the following schedules.
0 3 22-28 * 0
0 3 22-28 * 7
0 3 22,23,24,25,26,27,28 * 0
0 3 22,23,24,25,26,27,28 * 7
