No, this was an intentional design choice - we actually polled the community to find out what behaviour people wanted
here.Essentially, when the agent restarts it plays "catchup", and runs all the jobs it missed. It then recalculates the
newruntime for each that is always in the future. So, if you had an hourly job and the agent was down from 11:30 until
17:30,it would run the 12:00 instance of the job at startup (17:30) then resume the normal schedule at 18:00.

Got it thanks. I looked at the source and saw that was the case. I changed the startup script to go ahead and update
thenextrundate for all jobs to null (a trigger then takes care of setting it to the proper date). If I was polled, I
probablywould have made it a command-line switch to pgagent, or even make it configurable on a per-job basis. I have
somejobs that are critical they run at a particular time, others don't matter, maybe a couple that I would want to
catchup.
