Beats me. Tracing just your session without having to EXPLAIN each query (and therefore not get the output rows)? OK, I'm reaching. I tend to be very conservative about ripping things out that someone might want unless they're actually getting in the way of doing some new thing that we want to do - but so are you, and you know the history of this code better than I do. I'm happy to save my questioning for a more important issue. ...Robert -- Sent via pgsql-hackers mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
