pg_dump has code to figure out the dependency of objects in the
database so that the dump file produced can be restored. If one file
was output per table, how would you know in which order to restore
them? For example, you have a table with a FOREIGN KEY to reference
some other table, you need to restore the referenced table first.
That's true for both restoring the schema and restoring the data.
