The system enforces (or tries to) that a view can't be part of an inheritance hierarchy, but you seem to have managed to find a sequence of operations that avoids those checks. Turning a table into a view with a manual CREATE RULE operation has always been a kluge, and it's missing a check that the table isn't part of an inheritance tree. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
