    dump_command << "PGPASSWORD=#{config[:password]}" if config[:password].present?
    dump_command << "pg_dump"
    dump_command << "-d #{config[:database]}_backup"
    dump_command << "-t 'active_storage_*'"
    dump_command << "-U #{config[:username]}"

    return true if only_dump

    restore_command = []
    restore_command << "PGPASSWORD=#{config[:password]}" if config[:password].present?
