The OS and FS world is very, very different now than it was when
the Oracle and DB2 architectures were being crafted. What may have
been an excellent development effort then may not provide such good
ROI now.

Actually, the main "religious fanatic" I've seen recently is yourself.
While I have a gut feel that some of the issues you raise could
certainly do with further investigation, I'm not seeing that much from
you other than statements that muchof what postgresql does is wrong
(not "wrong for your Ron's use case", but "wrong in every respect").

A little less arrogance and a little more "here are some possibilities
for improvement", "here is an estimate of the amount of effort that
might be needed" and "here are some rough benchmarks showing the
potential return on that investment" would, at the very least, make
the threads far less grating to read.
