According to the man page that should have done it:
Note: Non-schema objects such as blobs are not dumped when -n is
specified. You can add blobs back to the dump with the

I guess the next question is 'what does postgresql considers a blob'?
bytea fields? How about a large text with megabytes worth of data?
