One point to that implementation is that in that design a step is globally declared to be blocking, but in reality that's the wrong way to see things: a step might block in some permutations and not others. So I think we should do as Michael suggested: it's the permutation that has to have a way to mark a given step as blocking, not the step itself. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
