You have to dump all the child tables; usually partitions are named reasonably such that a wildcard can do it:

pg_dump -t root_table_name\* > backup.sql

You don't exactly get a "flat" backup, as all the individual tables are included, but you do get it all into one file,
ifthat's good enough for you.
