The error happens when I try to create other temporary tables. Here is a part of my Server Log : ERROR: cache lookup failed for relation 463558 CONTEXT: SQL statement "CREATE TEMP TABLE Tmp_MsgRxOrder ( EventId int4, CodeRef int4 )" PL/pgSQL function "adm_ne" line 248 at SQL statement STATEMENT: SELECT ALIS.ADM_NE() >From what I understand, PostgreSQL is creating new temporary schemas or using existing one when I try to create a temporary table. The problem occurs when PostrgreSQL tries to use the pg_temp_4 schema. The oid of the tmp_d_alarm type is 463559. The pg_type table contains a record with relid = 463558 : typname | typnamespace | typowner | typlen | typbyval | typtype | typisdefined | typdelim | typrelid | typelem | typinput | typoutput | typreceive | typsend | typanalyze | typalign | typstorage | typnotnull | typbasetype | typtypmod | typndims | typdefaultbin | typdefault -------------+--------------+----------+--------+----------+---------+------ --------+----------+----------+---------+-----------+------------+---------- ---+-------------+------------+----------+------------+------------+-------- -----+-----------+----------+---------------+------------ tmp_d_alarm | 440012 | 104 | -1 | f | c | t | , | 463558 | 0 | record_in | record_out | record_recv | record_send | - | d | x | f | 0 | -1 | 0 | | This table was created inside a function with the following SQL : CREATE TEMPORARY TABLE Tmp_D_Alarm ( D_AlarmID int4 NOT NULL, D_RAlarmID int4 NOT NULL, D_PerceivedSeverity int4 NOT NULL, D_ObjRef int4 NOT NULL, D_ObjOwnerRef int4 NOT NULL, D_ObjClassTag varchar(5) NOT NULL, L_LogRecId int4 NULL ); There is no DROP command as this function is invoked from a connexion which is closed after calling this function. I guess that the temp table will be deleted as this is a temporary table. I tried the following : - REINDEX DATABASE alis; - DROP SCHEMA pg_temp_4 ( CASCADE ) - from the shell : reindexdb alis - Tried to stop/restart PostgreSQL, - vacuum Patrick ---------------------------------------------------------------------------- --------------- Patrick Fiche email : patrick.fiche@xxxxxxxxxxx tél : 01 69 29 36 18 ---------------------------------------------------------------------------- --------------- -----Original Message----- From: Tom Lane [mailto:tgl@xxxxxxxxxxxxx] Sent: lundi 23 mai 2005 15:18 To: Patrick.FICHE@xxxxxxxxxxx Cc: pgsql-general@xxxxxxxxxxxxxx Subject: Re: How to recover from : "Cache lookup failed for relation " Patrick.FICHE@xxxxxxxxxxx writes: > I have a server installed with Postgres 8.0.2 on Solaris. > Since two days, I get the error : "ERROR: cache lookup failed for = > relation > 463558" What SQL command(s) produce that error, exactly? > When I look with the pgAdmin at my database, I see that I have in = > pg_temp_4 > schema, a type called "tmp_d_alarm" which is the name of a temporary = > table > that I'm using in functions.... > The table of the same name is not in the schema and I suspect that this > remaining type is causing the trouble. Possibly. Does the pg_type.typrelid field of that entry contain 463558? How are you creating and dropping these temporary tables, exactly? > How to get read of this type.

What did you try, and what were the results? regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
