Well I complained about that at the time. At least for XML that's becuase you chose to make separate tags on separate lines for every single value instead of just having one tag for estimates, one for actual, and using attributes for the different values. Incidentally my patch to use getrusage also reraises the other issue I complained about. There's no organization to the tags so a tool to view them can't make heads or tails of them without knowing in advance what they all are. For example pgadmin can't make a tree with expandable subtrees for each data source since it doesn't know which attributes are related to which unless it hard codes knowledge about them. Tom pointedly ignored the getrusage thing -- presumably because it's well past the time to consider new patches. But I didn't post the example to discuss it, I posted it because I think it can inform these earlier decisions. Ie, seeing that data might make it clearer which things we want to be per-loop and which we want totals for. And knowing that we'll likely have a place to hang the total wall clock time if we want might make the decision easier. -- greg -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
