Yeah, the results shown in this thread are not very good :-(.  I'm
suspicious that the results are basically I/O-bound in your environment.
There might be some value in the cached-initdb-tree solution for slower,
more CPU-bound machines, but cutting out the regprocin overhead would
probably do just as much good there.
