Hi, I'm experiencing some strange trigger behaviour. Not sure if I'm simply missing something, or if I've run into a bug. create table t1 (id serial, toggle boolean); create table t2 (id serial, ref bigint); insert into t1 (toggle) values (false); insert into t1 (toggle) values (false); create trigger updateMe after update on t1 referencing new row new_row for each row when new_row.toggle = true insert into t2 (ref) values (new_row.id); update t1 set toggle = true where id = 1; After this update statement, I would expect to see *1* row in t2. Instead, I see two rows: +----+-----+ | id | ref | +====+=====+ | 1 | 1 | | 2 | 2 | +----+-----+ The "when" clause seems to be ignored entirely -- I can change to "when 1 = 0" and it'll still work. If I change the trigger to create trigger updateMe after update on t1 referencing new row new_row for each row insert into t2 (ref) values (new_row.id); something equally odd happens. Instead of doing an insert for each UPDATED row, it inserts a row for each row present in t1. This seems a bit odd to me, but again, I could just be misunderstand the way this is supposed to work. Documentation on triggers is a bit sparse I'm afraid... Any help on this issue would be more than welcome! - Bram
