Hi,
I am working on a performance issue with a partitioned table. Some of my sql
statements against this partition table is in waiting state for long time. I
have queried waiting=true in pg_stat_activity. Now, is there a way to find
out which sql is making other statements to wait.
Thanks for your help.

You probably need to take a look at pg_locks for details. If you
combine information from pg_locks, pg_stat_activity, and pg_class,
you can get a pretty good idea what's up.
