Fwiw at least pgadmin I don't think would be confused by this.

This is still pretty much true if only for the sheer unscalability of the amount of data being presented for users to sift through. I do want us to add a ton more instrumentation into the explain plan and this is only one small addition. If we add number of hard and soft i/os, time spent in user and system space, etc the result would be pretty unreadable and they're at least as important as things like this. -- greg -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
