Meh. The barriers to inventing new statements are already mighty tall.
As for (2), I agree there's risk of bugs, but what alternative have you
got that is likely to be less bug-prone? At least a reverse-list
capability could be tested standalone without having to set up a logical
replication configuration.
This should not be interpreted as saying I'm gung-ho to do this, mind
you. I'm just saying that if our intention is to support logical
replication of all DDL operations, none of the alternatives look cheap.
