Comment (by Gavin Wahl):
The other ticket is fixed, but it is still not possible to use expressions
in check constraints. The proposed workaround with lookups doesn't work
because my check constraint uses a function that takes multiple arguments
(I need to be able to do `CHECK num_nonnulls(a, b, c) = 1`).
