First, find the bad report:
evergreen=# select now()-query_start,procpid,current_query from
pg_stat_activity where current_query <> '<IDLE>';
?column? | procpid |
current_query
-----------------+---------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
00:00:00 | 24373 | select now()-query_start,procpid,current_query
from pg_stat_activity where current_query <> '<IDLE>';

SELECT\x09"6b89db56fc7d830b621fe56999f87eba"."shortname" AS "Library Short

\x09"7fb66fd46f5581428d27fcd56ad5c85f"."circ_modifier" AS "Circulation

(2 rows)
The second query is the baddy ... so:
evergreen=# select pg_cancel_backend(19681);
pg_cancel_backend
