slon currently uses READ ONLY ISOLATION LEVEL SERIALIZABLE DEFERRABLE for some
transactions, in particular the remote listener. This causes event propagation
to stall during another long running, serializable transaction.

I believe that only event creation and copy_set done against the origin require
serializable. The copy_set can use serializable deferrable. All other slon
transaction should work fine with isolation level repeatable read.
