Well, I'm afraid that transactions are too different from each
other. Currently, I experiment with
SELECT tup_returned + tup_fetched + tup_inserted + tup_updated +
tup_deleted FROM pg_stat_database WHERE datname='chantal';
not being sure whether this makes sense at all. ;-) For exmaple,
does "tup_fetched" imply "tup_returned"?
Tschö,
Torsten.
