Restoring a database restores to unexpected tablespace

Hi,

Can someone point me in the right direction for this issue we are having -- our goal is to dump a database that is currently on a tablespace named data2 that we want to restore on the same server but on tablespace pg_default -- we tried other ways like:
ALTER DATABASE "[database_name]" SET default_tablespace = [new_tablespace];
alter table all in tablespace data2 set tablespace pg_default;

But we want to try it with a pgdump/psql.

To reproduce on our end (Server 9.5):
1. create new database for the restore with the tablespace as pg_default
2. Dump the source database (currently on data2 tablespace) with the following command:
sudo -u postgres pg_dump mydatabase --no-owner --no-tablespaces | gzip > mydatabase.gz
3. Restore the database with this command:
zcat /var/backup/db/mydatabase.gz | sudo -H -u postgres psql --quiet -e -c 'SET default_tablespace = pg_default;' -f - mydatabase_test > /tmp/mydatabase_test.log

What happens during the restore is that all tables are created on data2, not pg_default.

Any help would be greatly appreciated.

Thanks,

Alex
