But have not been able to find any suggestion on how an end user can use to get around this problem. Basically, we have a table X, trying to drop it would result an error message below:
cache lookup failed for relation XXXXX
I am using PgAdmin and I can still view the schema of this table, but any operation on it would get the above error.
Any suggestion on how to drop a table in this situation.
I am also wondering whether this problem has been fixed in newer PostgreSQL releases.
