 -- Fortunately, Postgres does provide the expected functionality for arrays with other operators:

--- * Use @something = ANY($1)@ instead of @something IN ($1)@
--- * Use @something <> ALL($1)@ instead of @something NOT IN ($1)@
+-- * Use @some_expression = ANY($1)@ instead of @some_expression IN ($1)@
