psql and COPY

Peter, there seem to be problems with the COPY statement when psql is run
with redirected stdin.

If I have a file ${DUMPDIR}/dbdump.product containing:

COPY product FROM stdin;
05 \N 000000   \N \N S  D9 t  f  f  f  POLY BAGS-BLACK      .        Single   f
...
\.


and I run this command:
psql -e -d bray < ${DUMPDIR}/dbdump.product

no error messages are seen.

If I remove the COPY command from the file and run the COPY frpm inside
psql, I see the errors:

bray=> copy product from '/tmp/dbdump.product';
ERROR:  <unnamed> referential integrity violation - key referenced from 
product not found in brandname
