We don't have any facility to run a trigger on just any command, it
needs to be triggered by a table.  Of course, that's where your on
commit even triggers come in, presumably.  But for example, constraint
triggers support deferrability, which an on commit trigger wouldn't.
We'd just need DML triggers on any/no tables.
