In order to create a backup using pg_dump that is compatible with pg_restore you must use the --format=custom / -Fc when creating your dump.
From the docs:
Output a custom-format archive suitable for input into pg_restore.
So your pg_dump command might look like:
pg_dump --file /tmp/db.dump --format=custom --host localhost --dbname my-source-database --username my-username --password
And your pg_restore command:
pg_restore --verbose --clean --no-acl --no-owner --host localhost --dbname my-destination-database /tmp/db.dump
