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?
