If I am understanding this correctly, yes. They all share the same pid. The logline format is: log_line_prefix = '%t %d %u [%p]' and I believe %p represents the pid, and also that a pid corresponds to a backend. Therefore, same pid == same backend == same connection == same session. Many transactions within a session. -- Jon -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
