The same error happens additionally for views or materialized views.
Looking at the code, I think that we should just apply
ATSimplePermissions() on (ATT_TABLE | ATT_FOREIGN_TABLE) when
executing the detach command to check for the supported relkinds.
That would make the logic consistent with the attach code path that
does the same check on the partition attached, while generating an
error message already generic enough for this purpose.

Attached is a patch, with some regression tests.
