Unclear error message

In backend/commands/tablecmds.c, function ATAddForeignKeyConstraint, I find:

if (rel->rd_rel->relkind == RELKIND_PARTITIONED_TABLE)
{
    if (!recurse)
        ereport(ERROR,
                (errcode(ERRCODE_WRONG_OBJECT_TYPE),
                 errmsg("foreign key referencing partitioned table \"%s\" must not be ONLY",
                        RelationGetRelationName(pkrel))));

That message is wrong, because "rel" and not "pkrel" is the partitioned table.
I think it should be

        ereport(ERROR,
                (errcode(ERRCODE_WRONG_OBJECT_TYPE),
                 errmsg("foreign key cannot be defined on ONLY \"%s\" for a partitioned table",
                        Relatio
nGetRelationName(rel))));
