It looks like we're talking about two orthogonal projects here:
1. Test situations which require more than one connection, possibly
to different clusters, for example in the cases of Hot Standby and
Streaming Replication. This further divides into event-based and
time-based tests. It's this situation I had in mind when I posted,
and it was inspired by bugs I've seen, the most recent being in
writeable CTEs.
2. Test situations which require *many* connections in order to find
issues caused, in essence, by load.
Tsung seems well-suited to the latter.
Cheers,
David.
