Restoring A Dump As A Normal User

I want to be able to dump and restore my personal databases without
having to be the PostgreSQL super user, so I performed the following
step using a test database:

GOO:~ jeff$ pg_dump -O birthdays > dump.txt

I then dropped the database and did the following:

GOO:~ jeff$ createdb birthdays
CREATE DATABASE
GOO:~ jeff$ psql -d birthdays -f dump.txt
SET
SET
REVOKE
psql:dump.txt:14: ERROR: permission denied for schema public
SET
CREATE TABLE
CREATE VIEW
psql:dump.txt:57: ERROR: must be owner of schema public

The lines that failed in dump.txt, with line numbers added, are:

14. GRANT ALL ON SCHEMA public TO PUBLIC;
57. COMMENT ON SCHEMA public IS 'Standard public schema';

I looked at the resulting restored birthdays database, and it looks
correct. Do I need to worry about these error messages?

My entire dump.txt file is included below.

Thanks,

Jeff Flowers
