All, We've confirmed that this issue is caused by having long-running idle transactions on the server. When we disabled their queueing system (which prodiced hour-long idle txns), the progressive slowness went away. Why that should affect 9.X far more strongly than 8.4, I'm not sure about. Does that mean that 8.4 was unsafe, or that this is something which *could* be fixed in later versions? I'm also confused as to why this would affect BIND time rather than EXECUTE time.
One thing that this made me wonder is why we don't have transaction_timeout, or maybe transaction_idle_timeout.
