This query is wrong --- relfilenode is not a join column for any other
table. You should be using pg_class.oid there.
regards, tom lane
Thanks Tom.
I tried it using pg_class.oid and I still have some records which r
not in the pg_class files. What can I do about that?
(BTW what does relfilenode in pg_class stands for?)
Thanks again
Josh
relfilenode is the name of the actual file that holds the given
relation's data. Now that you've got that query right, can you give
us some more details about what's happening? Just to be sure, when
checking triggers, the query should be
select * from pg_trigger where tgrelid not in (select oid from
pg_class);
What are the queries that are generating these errors? Why are you
looking at pg_trigger? In order to help, we'll need to know more
about the situation that just the error type as different situations
can yield that. Do the same queries consistently yield the error?
Do you see the same oids in the errors, or do they change? Do you
use CLUSTER on any kind of regular basis? Have you had any other
kind of abnormal performance issues (other errors, system crashes,
etc...)? The more info you give, the better help you can receive.
