39.2. Event Trigger Firing Matrix - add note

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/12/event-trigger-matrix.html
Description:

39.2. Event Trigger Firing Matrix - add note to ALTER TABLE tag "see section
39.1. "
This section contains text
"The sql_drop event occurs just before the ddl_command_end event trigger for
any operation that drops database objects", which mean that there can be
different behavior on alter table ADD column and alter table DROP column,
for example.
This is not obvious by looking only at table in 39.2.

Thank you!
