Nope, you can do them now, you just have to spell everything out explicitly
for PostgreSQL:
http://postgresql.bteg.net/users-lounge/docs/7.1/programmer/rules-insert.htm

I believe the feature you are referring to is the automatic generation of
RULEs for INSERTing, UPDATEing and DELETEing from VIEWs.
