Re: cache lookup of relation 165058647 failed

I'v find out that this error occurs in:
 dependency.c file

2004-04-26 11:09:34 ERROR:  dependency.c 1621: cache lookup of relation
149064743 failed
2004-04-26 11:09:34 ERROR:  Relation "tmp_table1" does not exist
2004-04-26 11:09:34 ERROR:  Relation "tmp_table1" does not exist

in getRelationDescription(StringInfo buffer, Oid relid) function.

Any ideas what can cause this errors.
