Improved Query Performance and Compatibility Setting for Cluster Updates
Improved performance of queries with explicitly defined large sets. Added compatibility settinglegacy_column_name_of_tuple_literal. It makes sense to set it totrue, while doing rolling update of cluster from version lower than 21.7 to any higher version. Otherwise distributed queries with explicitly defined sets atINclause may fail during update. #25371 (Anton Popov).
