In that case it's not a locking problem, but just a resource-saturation
problem. I'm wondering if you are maxing out your disk drives'
throughput.
Are the slowdowns correlated with checkpoints? (Watch to see if there
is a postmaster child process spawned for checkpointing when it
happens.) Fooling with checkpoint intervals might help some, though
I suspect the only real answer will be 8.0's background-writer feature.
