He definitely shouldn't be able to do that, if not superuser.
However, after experimenting a bit it seems like pg_stats does work for
indexes as long as you are the owner of the index's table, which probably
explains why it took so long for anybody to notice the problem. Maybe the
OP is trying to look at the stats as a non-owner that's just been GRANT'ed
table access?
