Thanks, that's definitely something to consider.

I have been thinking of a sort of default list partition for the "rest" of
values. Would you rather declare that with something like the below than
having to enumerate all the values in a NOT IN list? Or the NOT IN way is
more intuitive/friendly?

CREATE TABLE _rest PARTITION OF table_name FOR VALUES [ IN ] DEFAULT

Of course, at most one such partition would be allowed.
