Wiki editor request

I would like editor access to the wiki, my username is amorris and I would like to modify https://wiki.postgresql.org/wiki/Lock_Monitoring

The existing query:

  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,         blocking_activity.query   AS current_statement_in_blocking_process   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        AND blocking_locks.relation IS NOT DISTINCT FROM blocked_locks.relation        AND blocking_locks.page IS NOT DISTINCT FROM blocked_locks.page        AND blocking_locks.tuple IS NOT DISTINCT FROM blocked_locks.tuple        AND blocking_locks.virtualxid IS NOT DISTINCT FROM blocked_locks.virtualxid        AND blocking_locks.transactionid IS NOT DISTINCT FROM blocked_locks.transactionid        AND blocking_locks.classid IS NOT DISTINCT FROM blocked_locks.classid        AND blocking_locks.objid IS NOT DISTINCT FROM blocked_locks.objid        AND blocking_locks.objsubid IS NOT DISTINCT FROM blocked_locks.objsubid        AND blocking_locks.pid != blocked_locks.pid    JOIN pg_catalog.pg_stat_activity blocking_activity ON blocking_activity.pid = blocking_locks.pid   WHERE NOT blocked_locks.granted;

does not work for cases where there are multiple transactions, it starts reporting additional bloced/blocking pairs that don't exist!

I have the following query that works for simple and complex cases with multiple transactions blocked by the same transaction:

SELECT    blocker.pid AS blocker_id,    blocker.datname AS blocker_db,    blocker.application_name AS blocker_app,    blocker.xact_start AS blocker_tx_start,    blocker.query AS blocker_cur_query,    --    blocked.pid as blocked_pid,    blocked.datname as blocked_db,    blocked.application_name AS blocked_app,    now() - blocked.query_start AS blocked_duration,     blocked.query as blocked_query
FROM pg_stat_activity AS blocked
JOIN pg_stat_activity AS blocker ON blocker.pid = ANY(pg_blocking_pids(blocked.pid))
order by blocked_duration desc;
