"-F format
--format=format

    Selects the format of the output. format can be one of the following:

    p
    plain

        Output a plain-text SQL script file (the default). 
    c
    custom

        Output a custom archive suitable for input into pg_restore. This is
the most flexible format in that it allows reordering of loading data as
well as object definitions. This format is also compressed by default. 
    t
    tar

        Output a tar archive suitable for input into pg_restore. Using this
archive format allows reordering and/or exclusion of database objects at the
time the database is restored. It is also possible to limit which data is
reloaded at restore time."
