Thread: How to profile an "SQL script"?
Hi. I have a longish collection of SQL statements stored in a file that I run periodically via cron. Running this "script" takes a bit too long, even for a cron job, and I would like to streamline it.
Is there a way to tell Postgres to print out, after each SQL statement is executed, how long it took to execute?
Thanks!

Do you run this with psql? You can switch on timing-output, with \timing. It displays after each statement the run-time for this statement. Andreas -- Really, I'm not out to destroy Microsoft.
