Well, there's something fishy about your results. Using CVS tip I see
about a 4-to-1 difference between COPYing 10000 rows and INSERT'ing
10000 rows (as one transaction). That's annoyingly high, but it's still
way lower than what you're reporting ...
I used the contents of table tenk1 in the regression database for test
data, and dumped it out with "pg_dump -a" with and without -d. I then
just timed feeding the scripts to psql ...
