What I meant is that if you do:

  CREATE TABLE p(i INT, j INT) PARTITION BY RANGE (i);
  CREATE TABLE p0 PARTITION OF p FOR VALUES FROM (00) TO (10);
  CREATE TABLE p1 PARTITION OF p FOR VALUES FROM (10) TO (20);
  CREATE INDEX p_idx ON p (i);
  CREATE INDEX special_idx ON p0 (j);
  GRANT MAINTAIN ON p TO foo;
  \c - foo
  REINDEX TABLE p;

That would reindex p0_i_idx and p1_i_idx, but skip special_idx. That
might be too confusing, but feels a bit more consistent permissions-
wise.
