On fast machines, it's possible for applications such as pgbench to issue connection requests so quickly that the postmaster's listen queue overflows in the kernel, resulting in unexpected failures (with not-very-helpful error messages). Most modern OSes allow the queue size to be increased, so document how to do that. Per report from Kevin McKibbin.
