Changing get_altertable_subcmdtypes() to return a set of rows made of
(subcommand, object description) is what I actually meant upthread as
it feels natural given a CollectedCommand in input, and as
pg_event_trigger_ddl_commands() only gives access to a set of
CollectedCommands.  This is also a test module so
there is no issue in changing the existing function definitions.

But your point would be to have a new function that takes in input a
CollectedATSubcmd, returning back the object address or its
description?  How would you make sure that a subcommand maps to a
correct object address?
