36.1 Overview of Trigger Behavior

Subparagraph 8:
I suggest to replace
"BEFORE row-level triggers to execute"
with
"row-level BEFORE triggers to execute"
for consistency.

Subparagraph 14:
While WHEN can be used with INSERT too, I suggest to replace
"However, in an AFTER trigger, the WHEN condition is
evaluated just after the row update occurs, and it determines
whether an event is queued to fire the trigger at the end of
statement."
with
"However, in an AFTER trigger, the WHEN condition is
evaluated just after the row inserted or updated, and it determines
whether an event is queued to fire the trigger at the end of
statement."
