Re: [PERFORM] slow deletes on pgsql 7.4

[Junaili Lie]

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,

J

What does EXPLAIN show for each of those cases?
