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 tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check".
