- as_rel_struct and as_rel_access combine into an as_rel_defined 
  (depth == 0 for all structure relations)
- additionally add as_rel_schema which defined which relations
  exists at all in the system (and hence can be used in as_rel_defined)

  legal and data size reasons we need a special DB operation "prune before
  epoch". Same perhaps for unreferenced data (still unused account, etc).

- select ac_oid,ac_description from as_account where ac_oid <= 1 order by ac_oid desc limit 1;
- select ac_oid,ac_description from as_account order by ac_oid desc limit 1;
