ON DELETE CASCADE with multiple paths in PostgreSQL 9.x

Hello!

We are using patched version of PostgreSQL 8.1 in order to work-around
bug described in
http://archives.postgresql.org/pgsql-bugs/2007-05/msg00130.php. Now, we
are going to upgrade to 9.0 and it also would be great to get rid of
patch as it makes keeping database engine current too expensive task.
I've checked 9.0 and it seems that undesirable behavior is still there.
Is there any plans to fix it in future releases? May be there are some
settings/workarounds that could help in this situation without patching
PostgreSQL server?
