Well, end-to-end testing would e better but we can test that the locks are
at least being recorded by white-box inspection:

postgres=# begin;
BEGIN
postgres=# select * from tellers for share;
 tid | bid | tbalance | filler 
-----+-----+----------+--------
   1 |   1 |        0 | 
   2 |   1 |        0 | 
   3 |   1 |        0 | 
   4 |   1 |        0 | 
   5 |   1 |        0 | 
   6 |   1 |        0 | 
   7 |   1 |        0 | 
   8 |   1 |        0 | 
   9 |   1 |        0 | 
  10 |   1 |        0 | 
(10 rows)

postgres=# select distinct age(xmax) from tellers;
 age 
-----
   0
(1 row)
