Furthermore, IIRC PostgreSQL's relatively slow connection creation time
has as much to do with other per-backend initialization work as it does
with the time to actually fork() a new backend. If there is interest in
optimizing backend startup time, my guess would be that there is plenty
of room for improvement without requiring the replacement of processes
with threads.
