Tom,
Thanks for the suggestion. I have just applied both switch , -f (I have
applied this in the previous case too) and -n, but it becomes slow again. At
the beginning it reads about 300 KB a second, and when it has read 1.5 MB,
it reads only about 10 KB a second, it slows down gradually. Maybe others
should also try this scenario. Can I help anything?
Best Regards,
Otto

I know it would be faster with COPY, but this is extremly slow, and the

What is the problem?
Hmm, does the Windows port have readline support, and if so does adding
the "-n" switch to the psql invocation fix the problem? Or you could
try feeding the script with -f switch or \i rather than "psql <script".
Readline adds a fair amount of overhead, which is completely invisible
at human typing speeds but can be annoying when reading scripts.
