Hi,

 

I have an application that creates temp tables to speed up the fetching of the data

Everything was working fine until a couple of days ago, the database is starting to display the following error more and more

 

cache lookup failed for relation 1852615815

 

I noticed that this error keeps displaying when several users access the system simultaneously

If I look up for this oid in pg_class I don’t find it, but I do find it in pg_depend. Is that normal ?

 

dragon=# SELECT * from pg_class where oid = 1852615815;

relname | relnamespace | reltype | relowner | relam | relfilenode | reltablespace | relpages | reltuples | reltoastrelid | reltoastidxid | relhasindex | relisshared | relkind | relnatts | relchecks | reltriggers | relukeys | relfkeys | relrefs | relhasoids | relhaspkey | relhasrules | relhassubclass | relfrozenxid | relacl | reloptions

dragon=# SELECT * from pg_depend where objid = 1852615815;

classid |   objid    | objsubid | refclassid | refobjid | refobjsubid | deptype

(1 row)

 

dragon=# SELECT pg_table_is_visible(1852615815);

ERROR:  cache lookup failed for relation 1852615815

 

 

Can anyone help please ?

What do I have to do to solve this issue ?

 

Thanks in advance
