[development] Database schema abstraction and *reflection* (was: Referential integrity -- finally?)

When doing a Firebird 1.x port of Drupal, I met a limitation of the
underlying DBMS with the node_access table, which can't be created with a
structure equivalent to the MySQL/PGSQL versions (see
for the workaround).

Would that level of abstraction enable us to use this type of solution (an
additional table f-keyed to a base table) ? It looks like iti wouldn't be
sufficient yet.
