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;
