It would be trivial to write a script in a language like Perl to
read the first line of a file and generate a CREATE TABLE statement
from it, then issue a COPY command and send the rest of the file.
Determining the columns' data types would be a different matter:
if they weren't specified in the header then you'd have to guess
or perhaps make them all text.

I've attached a sample implementation of Michael's suggestion.

I've attached what I hope is a slightly improved one :)
