This should do what you ask.
If the order does not matter, leave out the ORDER BY.
This assumes everything of interest is in the public schema.
$ createdb testdb
$ pg_dump realdb --schema-only | psql -q testdb
$ psql realdb
psql> \o dump.some.rows.sh
psql> select format($$psql realdb -c 'COPY (select * from %I order by 1 limit %s) TO STDOUT' | psql testdb -c 'COPY %I FROM STDIN' $$, table_name, 100, table_name)
from information_schema.tables where table_schema = 'public' and table_type = 'BASE TABLE';
psql> \q
$ sh dump.some.rows.sh
