How does this deal with row types with a field that doesn't have a hash function? Erroring out at runtime could cause queries that used to succeed, e.g. because all fields have btree ops, to fail, if we just have a generic unconditionally present hash opclass? Is that an OK "regression"?
Good point. There is actually code in the type cache that is supposed to handle that, so I'll need to adjust that.
