can't reindex a couple of tables

[I apologize if this message gets out twice. I accidentally sent the
first one from the wrong email address]

Hi,

We're having a problem with a couple of our tables.

I have 2 tables, attribute and attribute_value:

Table "public.attribute"
Column | Type | Modifiers
-----------------------+-----------------------+-----------
attribute_id | integer | not null
attribute_type | character varying(32) |
attribute_unit_id | integer |
click_count | integer |
feature_group | character varying(5) |
parent_attribute_id | integer |
promote_value | character varying(5) |
reference_category_id | integer |
sort_order | integer |
is_visible | character varying(5) |
Indexes:
"attribute_pk" PRIMARY KEY, btree (attribute_id)
"attribute__attribute_unit_id_fk_idx" btree (attribute_unit_id)
"attribute__parent_attribute_id_fk_idx" btree (parent_attribute_id)
"attribute__reference_category_id_fk_idx" btree
(reference_category_id)
Foreign-key constraints:
"attribute_attributeunit_fk" FOREIGN KEY (attribute_unit_id)
REFERENCES attribute_unit(attribute_unit_id) DEFERRABLE INITIALLY
DEFERRED
"attribute_parentattribute_fk" FOREIGN KEY (parent_attribute_id)
REFERENCES attribute(attribute_id) DEFERRABLE INITIALLY DEFERRED
"attribute_referencecategory_fk" FOREIGN KEY
(reference_category_id) REFERENCES category(category_id) DEFERRABLE
INITIALLY DEFERRED

Table "public.attribute_value"
Column | Type | Modifiers
-----------------------+----------------------+-----------
attribute_id | integer | not null
attribute_unit_id | integer |
attribute_value_id | integer | not null
boolean_value | character varying(5) |
click_count | integer |
do_keyphrase_matching | character varying(5) |
max_value | numeric(30,10) |
min_value | numeric(30,10) |
Indexes:
"attribute_value_pk" PRIMARY KEY, btree (attribute_value_id)
"attribute_value__attribute_id_fk_idx" btree (attribute_id)
"attribute_value__attribute_unit_id_fk_idx" btree
(attribute_unit_id)
Foreign-key constraints:
"attribute_value_attribute_fk" FOREIGN KEY (attribute_id)
REFERENCES attribute(attribute_id) DEFERRABLE INITIALLY DEFERRED
"attribute_value_attributeunit_fk" FOREIGN KEY
(attribute_unit_id) REFERENCES attribute_unit(attribute_unit_id)
DEFERRABLE INITIALLY DEFERRED

They both have a click_count column that we update with "update
attribute set click_count = click_count + 1;" and the same for the
attribute_value table. Postgres is getting hung up on any transaction
that attempts to update the click_count. I've vacuum analyzed both
tables and that worked fine. Now I tried to reindex them and Postgres
is just locking up and never finishing. I had to cancel the reindex.

The attribute table has only 3434 rows in it.
The attribute_value table has only 548735 in it.

Either one I try to reindex causes that Postgres connection to hang
until I cancel the reindex command.

Reindexing other tables works fine.

Are these two tables corrupt or something? Is there a way to fix
them? I thought about dumping them and re-loading them, but I don't
know how to do that due to all the referential integrity issues from
the other tables that reference these two tables.
