Обсуждение: Transactions within Function
I have a very basic function that performs several steps. Each one of these steps could take a significant amount of time which I would like to track.
To do this I am inserting a record to a logging table with a timestamp. After my function runs, all of my log entries have the exact same timestamp. I am assuming this is because they are all being committed in the same transaction.
Is there a way I can commit those log inserts in real time?

Use timeofday() rather than current_time. http://www.postgresql.org/docs/9.1/static/functions-datetime.html -- Andy Chambers Software Engineer (e) achambers@mcna.net
