This is probably an easy one for most sql users but I don't use it very often.

You could do it with pgpsql, or if your schema is too large generate a sript with it.
something like:
DO $$
DECLARE
test boolean;
rec record;
BEGIN
for rec in select tablename from pg_tables where schemaname = 'public'
LOOP
EXECUTE 'select exists (select * from public.'||rec.tablename||')' into test;
IF test THEN raise notice 'COPY public.% TO %.dump',rec.tablename,rec.tablename;
END IF;
END LOOP;
END;
$$ language plpgsql
