Comment:
The proposed solution makes sense to me, looks like #32392 was just a
workaround in the end.
It should be easy enough to add the conditional `f'({sql})'` wrapping if
`isinstance(expression, Col)` as you've mentioned (`Col` is
`django.db.models.expressions.Col`).
https://github.com/django/django/blob/225d96533a8e05debd402a2bfe566487cc27d95f/django/contrib/postgres/constraints.py#L72-L83
Would you be able to provide a patch/PR?
I also wonder if we should just revert the non-test bits of
fdfbc66331292def201c9344e3cd29fbcbcd076a since it might just be hiding
other instances of this problem.
