I guess it should show the relkind(%c) in the message, like these:

src/backend/commands/tablecmds.c:                       elog(ERROR, "unexpected relkind: %d", (int) relkind);
src/backend/tcop/utility.c:                                                             elog(ERROR, "unexpected relkind \"%c\" on partition \"%s\"",

ISTM reindex_index is missing that, too:

8b08f7d4820fd7a8ef6152a9dd8c6e3cb01e5f99
+       if (iRel->rd_rel->relkind == RELKIND_PARTITIONED_INDEX)
+               elog(ERROR, "unsupported relation kind for index \"%s\"",
+                        RelationGetRelationName(iRel));

Should say "..with REINDEX INDEX or REINDEX TABLE, respectively".

=> Each partition of the specified partitioned relation is reindexed in a
separate transaction.
