For DDL deparsing purposes, it seems important that the affected object
address can be reproduced somehow. I think pg_get_object_address()
should be considered, as well as the object_address test.
If we do as you propose, we would have to deparse
COMMENT ON CURRENT DATABASE IS 'foo'
as
COMMENT ON DATABASE whatever_the_name_is IS 'foo'
which is not a fatal objection but doesn't seem all that great.
