PostgreSQL release lock on table Edit

Below is the sample query to detect lock on PostgreSQL tables.

Sample Query

select nspname, relname, l.* 
from pg_locks l 
    join pg_class c on (relation = c.oid) 
    join pg_namespace nsp on (c.relnamespace = nsp.oid)
where pid in (select pid 
              from pg_stat_activity
              where datname = current_database() 
                and query != current_query());

If you run the above query you can find the PID & use the below command to terminate the backed

SELECT pg_terminate_backend(pid);
