ERROR: duplicate key violates unique constraint "pg_class_oid_index"
I found a post earlier but wanted to post up my info as the other persons did not look like the same type of error:
I tried to cluster the isbn_table
cluster isbn_index_code on isbn_table;
ERROR: duplicate key violates unique constraint "pg_class_oid_index"
ERROR: duplicate key violates unique constraint "pg_class_oid_index"
The table looks like this
Table "public.isbn_table"
Column | Type | Modifiers
---------+--------+-----------
item_id | bigint | not null
date | date |
code | isbn |
Indexes:
"isbn_pkey_item_id" primary key, btree (item_id)
"isbn_index_code" btree (code)
"isbn_index_date" btree (date)
"isbn_index_date_code" btree (date, code)
Triggers:
checkisbn BEFORE INSERT OR UPDATE ON isbn_table FOR EACH ROW EXECUTE PROCEDURE isbntrigger()
