That seems excessive to me too --- but it's fair to ask exactly what you
were counting; does that include system catalogs, or just these two
tables and their indexes?  It would help to see an ls -lR of the $PGDATA
directory and a map of the table numbers; you can make the latter with
    select relfilenode, relname from pg_class order by relfilenode;
