Commit 8aa9dd74b didn't quite finish the job in this area after all, because DROP ROLE has a code path distinct from DROP OWNED BY, and it was still reporting dependent objects in whatever order the index scan returned them in. Buildfarm experience shows that index ordering of equal-keyed objects is significantly less stable than before in the wake of using heap TIDs as tie-breakers. So if we try to hide the unstable ordering by suppressing DETAIL reports, we're just going to end up having to do that for every DROP that reports multiple objects. That's not great from a coverage or problem-detection standpoint, and it's something we'll inevitably forget in future patches, leading to more iterations of fixing-an- unstable-result. So let's just bite the bullet and sort here too. Discussion: https://postgr.es/m/E1h6eep-0001Mw-Vd@gemulon.postgresql.org

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
