Re: VACUUM FULL does not works.......

["Rajesh Kumar Mallah" <mallah(dot)rajesh(at)gmail(dot)com>]

We have a view in our database.


CREATE view public.hogs AS
SELECT pg_stat_activity.procpid, pg_stat_activity.usename,
pg_stat_activity.current_query
  FROM ONLY pg_stat_activity;

Select current_query from public.hogs helps us to spot errant queries
at times.
