On the machine performance.. I see no other problems.. There is almost
always no load on the processor/ram. I am not a great Unix guy.. but we
migrated from a 450 intel box running solaris 8 for intel to this box
about a month ago.. and so far the box has blown away the other box in
all aspects.. I do have postgres running on the old box.. but I never
did anything beyond the install.. maybe I'll play with it and see how it
runs (just to get some comparison). It is running 7.1.3 though..

a \i then the file name.. I have also tried using begin; and end; around

What OS are ya running? Just wondering. It's not Windows and cygwin,
right?
Take a look at the output of your system logs to make sure you aren't
getting massive bus errors or running low on memory or something
strange.
My Postgresql boxes can import about 4 to 10 thousand rows a minute,
with
full PK indexes in place (dual PIII-750 with 512 Meg ram, nothing
amazing.) Single drive no less.
Sounds like something is definitely wrong with your box or your
postgresql
install.
Are you running 7.2.x?
