There is a default built-in role `pg_monitor` and the behavior changed after the patch. If `\dg+` and `\du+` is treated as the same, and `make check` all pass, then I assume there is no test case to verify the output of `duS+`. My point is should we consider add a test case?
I mean, either you accept the change in how this meta-command presents its information or you don't. I don't see how a test case is particularly beneficial. Or, at least the pg_monitor role is not special in this regard. Alice changed too and you don't seem to be including it in your complaint.
