Just had a need for this feature, and took this to a short test drive. So some comments: - it'd be useful to display a retry percentage of all transactions, similar to what's displayed for failed transactions. - it appears that we now unconditionally do not disregard a connection after a serialization / deadlock failure. Good. But that's useful far beyond just deadlocks / serialization errors, and should probably be exposed. - it'd be useful to also conveniently display the number of retried transactions, rather than the total number of retries. Nice feature! - Andres -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
