In what way ?

Do you mean that it will be easy for the user to make errors, od do yuo
think that it will be hard to implement in a robust way ?

In the first case, I'd propose following syntax

ALTER TABLE childN ALTER INHERITS DROP (parent);
ALTER TABLE childN ALTER INHERITS ADD (parent);

With this syntax reparenting would need an explicit transaction and two
"ALTER TABLE ... ALTER INHERITS ..." commands, but it is (arguably)
harder to make mistakes.
