If you have something deadlock blocking a table in Redshift, you can run this query to help find out what's happening:

select a.txn_owner, a.txn_db, a.xid,, a.txn_start, a.lock_mode, a.relation as table_id,nvl(trim(c."name"),d.relname) as tablename, a.granted, as blocking_pid ,datediff(s,a.txn_start,getdate())/86400||' days '||datediff(s,a.txn_start,getdate())%86400/3600||' hrs '||datediff(s,a.txn_start,getdate())%3600/60||' mins '||datediff(s,a.txn_start,getdate())%60||' secs' as txn_duration from svv_transactions a left join (select pid,relation,granted from pg_locks group by 1,2,3) b on a.relation=b.relation and a.granted='f' and b.granted='t' left join (select * from stv_tbl_perm where slice=0) c on left join pg_class d on a.relation=d.oid where a.relation is not null;

Kill it with:

select pg_terminate_backend(323);
