Interesting. I'm not sure how to read the graph however -- for example what does it mean to have ReadyForQuery in both a rectangle and an ellipse? What do the standalone boxes mean? (e.g. the SSLRequest and CancelRequest? and why are they wrapped in two boxes? why Close/CloseComplete appear from nowhere and they don't lead anywhere?) Maybe it would make more sense to have a graph of states, and the edges would indicate what messages are sent to change from one state to another. -- Alvaro Herrera http://www.CommandPrompt.com/ PostgreSQL Replication, Consulting, Custom Development, 24x7 support ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
