Re: strange query results

Hi tom
The table description is as follows

arttoday=> \d exhibit_distributions
Table "exhibit_distributions"
Attribute | Type | Modifier
------------------------------+---------------+------------------------------------------------------
exhibit_distribution_id | integer | not null default nextval('sq_exhibit_dist_id'::text)
exhibit_id | integer | not null
created_by | integer | not null
creation_date | timestamp | not null default "timestamp"('now'::text)
last_update_date | timestamp |
last_updated_by | integer |
exhibit_type_id | integer | not null
medium | varchar(100) |
image_path_small | varchar(50) |
image_path_big | varchar(50) |
length | numeric(7,2) |
breadth | numeric(7,2) |
width | numeric(7,2) |
diameter | numeric(7,2) | default 8
dimensional_aspect | varchar(50) | default 'Dimensions'
unframed_volume_weight | numeric(10,2) |
framed_volume_weight | numeric(10,2) |
override_vw_computation | boolean | default 'f'::bool
exhibit_code | varchar(25) |
exhibit_options | varchar(10) |
unframed_exhibit_restriction | varchar(25) | default 'WORLD'
framed_exhibit_restriction | varchar(25) | default 'WORLD'
up_for_sale | char(1) | not null default 'T'
gallery_id | integer |
site_section | varchar(20) | not null default 'GALLERY'
Index: exhibit_distributions_pkey
Constraints: ((up_for_sale = 'T'::bpchar) OR (up_for_sale = 'F'::bpchar))
(length > '0'::"numeric")
(breadth > '0'::"numeric")
(width > '0'::"numeric")
(((unframed_exhibit_restriction = 'WORLD'::"varchar") OR (unframed_exhibit_restriction = 'INDIA'::"varchar")) OR (unframed_exhibit_restriction = 'ONLY_WORLD'::"varchar"))
(((framed_exhibit_restriction = 'WORLD'::"varchar") OR (framed_exhibit_restriction = 'INDIA'::"varchar")) OR (framed_exhibit_restriction = 'ONLY_WORLD'::"varchar"))
(((exhibit_options = 'FRAMED'::"varchar") OR (exhibit_options = 'UNFRAMED'::"varchar")) OR (exhibit_options = NULL::"varchar"))

Explain plan results in the following
arttoday=> explain select site_section, count(*) from exhibit_distributions group by site_section;
NOTICE: QUERY PLAN:

Aggregate (cost=69.83..74.83 rows=100 width=12)
-> Group (cost=69.83..72.33 rows=1000 width=12)
-> Sort (cost=69.83..69.83 rows=1000 width=12)
-> Seq Scan on exhibit_distributions
(cost=0.00..20.00 rows=1000 width=12)

The problem still persists.. I will a drop and recreation of the db just
in case..

Thanks for the help
Anand
