Perhaps it would help if an errhint is added which is written as "This
relation is a %s", where %s is a relkind converted to a translatable
string describing the kind?  All those modules work on different objects
and have different goals and prospoectives, so it looks difficult to me
to come up with a sane API which is rather portable across modules.

The statu-quo is not completely bad either (aka no extra error
messages) as incorrect relation kind are still filtered out, perhaps the
docs don't emphasize enough that an index and a partitioned index are
two different things?
