Yeah, but he doesn't want to have to create the table before hand, he wants
postgresql to do all the work. ;)

The only way that I know of to do that is write a program and feed it the
CSV file... but in the program it is going to need to create the table.

Sometimes you just have to do the work yourself. :)
