It's difficult to say for sure when you haven't showed us exactly what
you did, but one possibility is that you created the relations inside
a transaction and then forgot to commit the transaction before quitting.
Or perhaps you're creating them in a different database or different
schema than where you're subsequently looking. Note that \d without
any parameter will only show relations that are in your current
search_path.
