psql reading from stdin

Hi

I was trying to populate the database in Windows by doing psql -f dumpfile.
It creates the tables just fine and executes the SET commands in the file,
but it ignores all the data given as COPY xxxx (xxx,xxx,xxx) FROM stdin;
commands.

\i dumpfile at the psql prompt also doesn't work.

To work around this, the dump file can be generated with pg_dump -D, meaning
store the data as INSERT commands rather than COPY. But something is
apparently wrong with the stdin of psql in Windows.
