Can you show the definition of the table on both system?  Also did you add some
extension or created some casts?  I'm wondering if your problem is that you're
actually executing something like that:

UPDATE table_name SET column1 = (1::bool AND column2 = 2) WHERE id = 1;

due to implicit int - bool cast, which aren't present in you pg12 instance (and
shouldn't be present in vanilla postgres).
