ERROR: XX000: cache lookup failed for relation

Hi chaps,

I've got a problem trying to drop a table, I get the error "cache lookup failed for relation"

SEE=# drop table replicated_users;
ERROR: XX000: cache lookup failed for relation 30554884
LOCATION: getRelationDescription, dependency.c:2021
Now this table is on a slony-I slave and was in replication when I tried to drop it - I presume this is a big mistake and I should never try to drop a table without first droping it from replication?

In addition I'd set up a trigger on the table "replicate_users".

If I do:

select relname,oid from pg_class where relname = 'replicated_users';

-[ RECORD 1 ]-------------
relname | replicated_users
oid | 30554879

Thats not the same oid as the one it's complaining about.

Does anyone have any idea why this has happened or how I can fix it?

Cheers
Glyn
