check if the same function is already running, then exit!
Before running a running a function, i would check only 1 instance is
running. If alreaady a function is running, the existing function should
exist with the msg that already a function with same is running.
If somebody has already used such a faeture, can u please share or
Can you tell me the table and column from which I could this info.
Thanks,

Advisory locks might work for you:

(at the bottom of the page)
google will find other's talking about it: "postgres advisory lock"
