Hi,
I have a table containing 8 rows. The records are around 2k max.
selects on this table take very long to complete:
This is not a table that had a lot of adds/deletes, and I
have run vacuum and analyze.
tium=# select count(*) from trunk;
count
-------
8
(1 row)
(Takes about 2 seconds)
The database is lightly loaded otherwise, but I don't understand
the explain output:
tium=# explain select count(*) from trunk;
QUERY PLAN
---------------------------------------------------------------
Aggregate (cost=65598.10..65598.11 rows=1 width=0)
-> Seq Scan on trunk (cost=0.00..65598.08 rows=8 width=0)
(2 rows)
What does it mean that the cost figures are so high?
This is a standard run-of-the-mill server by the way with 1GB RAM,
I have shared buffers set to 12000.
Thanks,
Ron
