creates too much overeat and a lot of additional code (especially if
there are a lot of such dependencies). Array support in Postgres is
quite handy; in my practive, moving from a_b_map to arrays economizes
hundreds of lines of stored procedure and calling application code.
Triggers are not very helpful here, because it is too boringly to
control that all needed tables has appropriate triggers (we need N + 1
triggers with unique code, where N is the number of referring tables).
So, built-in support looks much more interesting...
