I think we could replace this whole table by a few definitions:

- "Local objects" are everything except "global objects".

- "Global objects", for the purpose of event triggers, are databases,
tablespaces, roles, role memberships, and parameter ACLs.

- DDL commands are all commands except SELECT, INSERT, UPDATE, DELETE,
MERGE.

- Events triggers are supported for all DDL commands on all local objects.

Is this table saying anything else?

Is there any way to check if it's even correct? For example, it shows
that the event "sql_​drop" can fire for a few ALTER commands, but how is
this determined? If tomorrow someone changes ALTER DOMAIN to possibly
do a table rewrite, will they remember to update this table?
