Hi, everybody!
Running the same query on pg 8.2 through EXPLAIN ANALYZE takes 4x-10x time as
running it without it.
Is it ok?
Example:
testing=> select count(*) from auth_user;
count
---------
2575675
(1 row)
Time: 1450,829 ms
testing=> explain analyze select count(*) from auth_user;
QUERY PLAN
----------------------------------------------------------------------------------------------------------------------------
Aggregate (cost=89814.87..89814.88 rows=1 width=0) (actual
time=18460.436..18460.439 rows=1 loops=1)
-> Seq Scan on auth_user (cost=0.00..83373.89 rows=2576389 width=0)
(actual time=0.424..9871.520 rows=2575675 loops=1)
Total runtime: 18460.535 ms

TIP 6: explain analyze is your friend
