I could live with stddev. But we really ought to be investing in making pg_stat_statements work well with third-party tools. I am very wary of enlarging the counters structure, because it is protected by a spinlock. There has been no attempt to quantify that cost, nor has anyone even theorized that it is not likely to be appreciable. -- 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
