Ingres has table names as numbered files. It is a pain to figure out
which files match which tables. If you need to restore a table from
tape, the pg_class entry is gone and you have no way to figure out the
right table. When analyzing disk space, figuring who is using the space
is a pain.
Every Ingre admin I ever talked to agreed file numbers are a pain.
