This is an 8.0 bug fixed in 8.0.1.

This is because plpgsql caches plans and therefore can't cope with
tmp_table not being the identical same table from run to run of the
function. Sooner or later we will probably fix that, but in the
meantime consider using an ON COMMIT DELETE ROWS temp table, created
only once per connection, instead.
