Обсуждение: How can I make note of time taken by each query to execute in Triggers

Hi All,
I would like read time taken by each query in my triggers.
so i created a temporary table and inserted timestamp before i start qurey
and inserted again timestamp after completion of the query. But i am getting
same time. How can I get the time taken by each query.

Regards,
Sreedhar

One of the options you can specify in postgresql.conf, is to write to log the
amount of time of each query.  That should give you the precision you need,
although of course you need to look at a log file and not at a DB table...

If you try this approach, I recommend you specify printing out the queries as
well, that will allow you to distinguish what is taking how long.
