Nice work! There is one feature I'd like to request -- we need to be able
to also track nested statements. This would greatly simplify diagnosing
performance problems in complex stored procedures. Perhaps the GUC
track_statements could be made an enum - none, top, all?

PS. Similar feature would be useful for auto-explain as well.
