This whole sockets conversation has wandered way off topic. PostgreSQL
runs into high-connection scaling issues due to memory limitations (on
Windows in particular, as noted in the FAQ entry I suggested), shared
resource contention, and general per-connection overhead long before
socket issues matter.
