That's exactly what i'm working on. Currently I have a stored procedure
pg_create_view_updrule() that takes the OID of the view _RETURN rule and
forms
an INSERT rule from it (DELETE/UPDATE are not yet implemented). To get down
the query trees is a bit complex, but it seems to work right now, although
there's many i have to do in the next days.....i will post as soon as I
have a working proof-of-concept. Please note that i'm heading for
SQL92-compliance, SQL99 seems a todo for the next-generation.
