And 7.5 will print out a more helpful message if you forget to set
these:

 test=> select * from pg_stat_activity;
  datid | datname | procpid | usesysid | usename  |        current_query         | query_start
 -------+---------+---------+----------+----------+------------------------------+-------------
  17227 | test    |   15527 |      100 | guest    | <command string not enabled> |
  17227 | test    |   15574 |        1 | postgres | <insufficient privilege>     |
 (2 rows)
