I'm beginning to think there is something seriously messed up about your
installation. The simplest theory is that the indexes on pg_attribute
are corrupted. You could try a query that won't use the indexes, eg

select (select relname from pg_class where oid = attrelid)
from pg_attribute where attnum = 1 order by 1;

and look through the output to see if temp_event and the other broken
table are mentioned. If so, then the rows are there but the index is
wrong. You should be able to recover using REINDEX --- read the
reference page for it carefully before executing the recovery procedure!

If that doesn't work, re-initdb and re-importation of your dump would be
a good next step. Something must have dropped a bit somewhere...
