I'm wondering exactly where/how the duration was measured. If it was at a client, maybe the apparent delay had something to do with network glitches? It seems suspicious that all the outliers are around 0.8s. It would be useful to look to see if there's any comparable pattern for statements other than BEGIN. As Richard says, a BEGIN by itself ought to take negligible time. regards, tom lane -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
