True, Just checked that.

pg_prewarm extension works on index if we have right (SELECT) privileges
postgres=# CREATE TABLE x(id INT);
CREATE TABLE
postgres=# CREATE INDEX idx ON x(id);
CREATE INDEX
postgres=# INSERT INTO x SELECT * FROM generate_series(1,10000);
INSERT 0 10000
postgres=# SELECT pg_prewarm('x');
pg_prewarm
------------
45
(1 row)
postgres=# SELECT pg_prewarm('idx');
pg_prewarm
------------
30
(1 row)

True, adding Robert Haas (author) to this thread for his opinion.
