No, there are two different cases being dealt with here. If the first call of an expression results in an error, and then we come back and try to re-use the expression state tree, we can have trouble because the state tree contains partially-updated internal state for the called function. This doesn't require any recursion but it leads to pretty much the same problems as the recursive case. regards, tom lane -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
