*Repro steps*
1. Create a database which has circular foreign key dependencies. (or use
the sql script which I have shared), restore the pre-data section first.
2. pg_dump -Fc *--section=post-data*
3. pg_restore --jobs > 1
pg_restore fails to record the dependency between the foreign keys and
tries to process them in parallel (see the attached log file for details)
