Re: A costing analysis tool

I'm not interested in storing less information. I'm trying to make sure
that all redundant information is justified. Since I plan to store the
actual query text and the full EXPLAIN ANALYZE output, every
column I pull out and put in another table is redundant data. The
questions are, why do we have it, is it going to be used heavily
enough in such a way that it should be stored redundantly? If the
goal is to be able to get at the number of filters, etc., perhaps
another
table which digests this to a form which can be used in summary
queries is what's needed. If this is a rare type of query which few
people will run, maybe they can go to the EXPLAIN ANALYZE,
using the line number info, and grab it from there.

I'm also really unclear on why you're so focused on storing less
information rather than more. In an "investigation" tool like this,
it's
important to collect as much data as possible because we don't know
what's
going to be valuable until we analyze it. You seem to be starting out
with the idea that you *already* know exactly where the problems are
located, in which case why develop a tool at all? Just fix the problem.
