We got a problem ticket from the customer. Messages in the error_log indicated problem trying to insert a duplicate value into a table. Looking at the database (v.7.3.2 on Solaris) I'm puzzled with this:
syncdb=# \d ERROR: Cache lookup failed for relation 17075 syncdb=# \di ERROR: Cache lookup failed for relation 17081 syncdb=# \d property_types; ERROR: Cache lookup failed for relation 17075 syncdb=# \d public.property_types Table "public.property_types" Column | Type | Modifiers -------------+-------------------------+----------- id | integer | not null name | character varying(256) | not null stamp | date | not null description | character varying(1024) | Indexes: pt_pk primary key btree (id), pt_name_uid_uk unique btree (name) syncdb=# SET search_path = public, pg_catalog; SET syncdb=# \d property_types; ERROR: Cache lookup failed for relation 17075 syncdb=# select * from pg_namespace ; nspname | nspowner | nspacl ------------+----------+-------- pg_catalog | 1 | {=U} pg_toast | 1 | {=} public | 1 | {=UC} pg_temp_1 | 1 | (4 rows) syncdb=# select * from property_types; id | name | stamp | description ----+------+-------+------------- (0 rows) INSERT INTO property_types (id, name, description, stamp) VALUES (nextval('pt_seq'), 'FROM_RELATIONSHIP', 'Describes the relationship of ...', date('today')); ERROR: Cannot insert a duplicate key into unique index pt_name_uid_uk --------------------------------------------- I can only guess that something is corrupted. What could lead to that? Can this can be prevented or repaired? Thank you, Mike. ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
