Tom's response is certainly something to consider; also, note that if
you "pg_dump -t" each table separately, the dumps are not necessarily
consistent with one another, meaning that you could end up with an
unrecoverable backup if a transaction modifying two (foreign key-)
dependant tables happens to run after backing up one but before backing
up the other.
