the timing of the trigger firing can be adjusted using SET CONSTRAINTS.
Constraint triggers must be AFTER ROW triggers on tables. They can be
fired either at the end of the statement causing the triggering event,
or at the end of the containing transaction; in the latter case they are
said to be deferred. A pending deferred-trigger firing can also be
forced to happen immediately by using SET CONSTRAINTS. Constraint
triggers are expected to raise an exception when the constraints they
implement are violated.

OK, timing of constraint triggers is explained.
But I think the docs don't state the timing of normal AFTER triggers.
Or am I blind?
Look about seven paragraphs up from the one you show above.
