As long as any new field in the Counters struct needs to be protected by a spinlock, I will be suspicious of the cost. The track_io_timing stuff is still protected, even when it's turned off. So I'm afraid that it isn't that simple. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
