Remove crude hack that tried to propagate collation through a function-returning-record, ie, from the function's arguments to individual fields selected from its result record. That is just plain inconsistent, because the function result is composite and cannot have a collation; and there's no hope of making this kind of action-at-a-distance work consistently. Adjust regression test cases that expected this to happen. Meanwhile, the behavior of casting to a domain with a declared collation stays the same as it was, since that seemed to be the consensus.
