I think you are confusing this for "here is a completely different plan
for a completely different query that has nothing to do whatsoever to
what I was asking before".

On this plan it looks like you need an index on otid. Or maybe not.
It's hard to tell with only an EXPLAIN.

Here is the OUPTPUT from EXPLAIN ANALYSE

 HashAggregate  (cost=5893012.31..5893014.28 rows=158 width=32) (actual time=829.511..829.511 rows=0 loops=1)
   ->  Hash Join  (cost=215823.74..5892929.49 rows=5521 width=32) (actual time=829.502..829.502 rows=0 loops=1)
         Hash Cond: ("outer".deliveryid = "inner".deliveryid)
         ->  Seq Scan on sms_new  (cost=0.00..5036990.11 rows=128012086 width=8) (actual time=8.620..8.620 rows=1 loops=1)
               Filter: ((otid)::text !~~ 'ERROR%'::text)
         ->  Hash  (cost=215823.35..215823.35 rows=158 width=32) (actual time=820.865..820.865 rows=0 loops=1)

                     Recheck Cond: ((createddate >= '2007-12-11 00:00:00'::timestamp without time zone) AND (createddate <= '2007-12-11 23:59:59'::timestamp without time zone))
