but if i have "on delete cascade" constraint,
in that case if i have a trigger which is fired in case delet happens on the table y.

i have a table x, and table y has a foreign key with "on delete cascade" constraint,

now i delete a row from x, will the trigger still be called?

By default, no, but there is the CASCADE option ...
