Yeah, that's right, normal users can't view the fields like query,
state, state_change, client details , xact_start time, query_start
time e.t.c. All he can see is, may be the database and user related
stuffs. You may try running 'select * from
pg_stat_get_activity(NULL);' to know on what all fields appear to be
null for normal users. The system view pg_stat_activity eventually
collects data from pg_stat_get_activity and shows it the users. Also,
please note that normal user can't reset the stats. You would get a
permission denied error when trying to run pg_stat_reset() function as
a normal user. Thanks.
