I fiddled around a while, found the problem, and I can repeat it at
will. It's actually related to type changes we've made over the months
since the restore.
Scenario:
1. Create a table as user A.
create table toaster (
bread varchar(8000)
);
2. Check typowner of toast type
# select typowner from pg_type join pg_class on (typname=relname) where
pg_class.oid in (select reltoastrelid from pg_class where
relname='toaster');
typowner
----------
16388
3. Alter the field type
alter table toaster ALTER bread type varchar(9000);
4. Check the typowner of toast type
# select typowner from pg_type join pg_class on (typname=relname) where
pg_class.oid in (select reltoastrelid from pg_class where
relname='toaster');
typowner
----------
3555301
The table and toast table owners are not affected:
# select relowner from pg_class where relname='toaster';
relowner
----------
16388
# select relowner from pg_class where oid in (select reltoastrelid from
pg_class where relname='toaster');
relowner
----------
16388
Hope this helps.
