B.5.9: Can triggers access tables?

A trigger can access both old and new data in its own table. A trigger can also affect other tables,
but it is not permitted to modify a table that is already being used (for reading or writing) by the statement that invoked the function or trigger.

The trigger cannot modify the table on which it has been fired.
