Обсуждение: How to echo statements in sourced file?
Hi. I have a 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 profile it.
I learned from Andreas Kretschmer (in another thread, in the pgsql-performance list) about the \timing directive, which is useful for this.
Now, after turning timing on, when I "source" the script from within psql, with
mydb=> \i /path/to/my/script
...I get output lines like this
Time: 38.519 ms
right in my psql terminal after each statement in the file gets executed.
But now I need a way to have these statements that are being timed themselves echoed to the terminal. Is there a way to do this?
TIA!

start psql with the -a switch, I think.

Thank you all. From your replies I was able to figure out what I needed: "\set ECHO queries"
