zkuste zjistit, kdo přesně vás blokuje s tímto prohlášením :
SELECT blocked_locks.pid AS blocked_pid,
blocked_activity.usename AS blocked_user,
blocking_locks.pid AS blocking_pid,
blocking_activity.usename AS blocking_user,
blocked_activity.query AS blocked_statement,

blocked_activity.application_name AS blocked_application,
blocking_activity.application_name AS blocking_application
FROM pg_catalog.pg_locks blocked_locks
JOIN pg_catalog.pg_stat_activity blocked_activity ON blocked_activity.pid = blocked_locks.pid
JOIN pg_catalog.pg_locks blocking_locks
ON blocking_locks.locktype = blocked_locks.locktype
AND blocking_locks.DATABASE IS NOT DISTINCT FROM blocked_locks.DATABASE

WHERE NOT blocked_locks.GRANTED;
blocking_pid
je pid, který chcete ukončit
Můžete zkontrolovat, zda je váš výpis blokován smbd pomocí kratšího qry:
t=# select datname,pid,usename,query from pg_stat_activity where waiting ;
datname | pid | usename | query
---------+-------+----------+---------------------
t | 30930 | postgres | select * from so24;
(1 row)
Aktualizace:pro 9.6 sloupec čekání bylo nahrazen s wait_event a wait_event_type, takže dotaz bude
select datname,pid,usename,query from pg_stat_activity where wait_event is not null;
