Hi Juan,

Why don't you do a COPY FROM STDIN?  You could import these records
in a few minutes time over the LAN or even the internet.  I do 5
million records in less than 3 minutes this way over localhost on a
PowerBook G4 550 MHz.

It's also recommended to drop your indexes while you do such large
inserts/imports.  (Create them again afterwards of course.)
