I tried this real quick at the psql command prompt, and unfortunately it
doesn't work:
mydb=# select ('1' || repeat('0',7))::bit varying;
ERROR: cannot cast type text to bit varying
I appreciate the try though. Any other ideas? I am using PostgreSQL
8.2.3.1. I don't know if that matters too much.
Thanks,
Ed

Try casting from a string:
SELECT ('1' || repeat('0', n-1))::bit varying;
