It was on my first email.
Here it is again:
MONSOON=# explain delete from scenario where id='1099';
QUERY PLAN
------------------------------------------------------------------------------
Index Scan using scenario_pkey on scenario (cost= 0.00..3.14 rows=1 width=6)
Index Cond: (id = 1099::bigint)
(2 rows)
MONSOON=# explain delete from scenario where id='1023';
QUERY PLAN
------------------------------------------------------------------------------
Index Scan using scenario_pkey on scenario (cost=0.00..3.14 rows=1 width=6)
Index Cond: (id = 1023::bigint)
(2 rows)
Thanks,

What does EXPLAIN show for each of those cases?
