Subject: Nonexistent NEW relation in some places of rules

Message-ID: <20030730033328.B4870@natasha.ward.six> (raw)
In general, the task I'm trying to solve is to make a multiply inserts
for a table on the one only insert for a view. It should be noted
about the method of producing these multiply rows, that they depend on
the VALUES given to that <top level> INSERT. So, the trivialized
schema is:
create function produce (text) returns setof text
language plpgsql
as '
begin
return next $1||1;
return next $1||2;
return next $1||3;
return;
end;
';
create table a (a text);
create view b as
select a as b
from a;
create rule b as
on insert to b do instead
insert into a
select * from produce (new.b);
And I get
psql:zhoppa.sql:21: ERROR: Relation "*NEW*" does not exist
when I feed this to psql...
So, what is wrong in using NEW right from the FROM?
Thanks in advance.
