Yeah. This is blatantly obviously the brainchild of some person
with no actual experience in fulfilling the roles they want to
circumscribe.

Having said that, maybe:

* Role foo_owner actually owns the tables, but revokes its own
DML privileges (select etc)

* Role foo_app is granted foo_owner so it can do DDL on the
tables, and is also granted DML privileges on the tables

* Role foo_dba is granted foo_owner but not DML privileges.

This is, of course, trivially breakable by any foo_dba who
doesn't want to play by the rules, but as long as you log
DDL there will at least be log traces that she did so.
