I think the uses could be many. Keep track, on a per 'backend'
basis, max memory used during the life of the process, so that you can
estimate memory requirements/upgrades. Average query times for the
duration of the process? Or maybe even bring it down to a 'per query'
logging, so that you know what the query was, how long it took, and what
resources were required? Tie that to a table of processes, maybe with a
timestamp for when the process started up and when it started.
Then, using a simple query, you could figure out peak times for
processes, or number of processes per hour, or...
