I found that it was actually a '\\N' value only that causes dumps to dump successfully, but fail on import (When using COPY), because both '\N' and '\\N' are seen as null by the COPY statement. I just happened to have '\\N' values in my NOT NULL text field. I now manually use this dump command : pg_dump | sed 's:\\\\N:�:g' | gzip > dump.gz
and do the reverse sed to restore.

=> => query? How are you restoring the data? psql?
=>
=> Dumping:
=> pg_dump -Ft | gzip > dump.tgz
=>
=> Restoring:
=> zcat dump.tgz | pg_restore -Ft |psql
=> OR
=> tar xvfz dump.tgz
=> perl -pi -e 's/\$\$PATH\$\$/$ENV{PWD}/g' restore.sql
=> psql -f restore.sql
=>
=> Both these methods, produce the same result.
