I've been able to reproduce the bug on 9.0 stable as well, using the
OP's test script.
Multiple errors like this...

ERROR: relation "pgbench_accounts" does not exist
STATEMENT: alter table pgbench_accounts set (fillfactor = 100);

Presume we want to fix both bugs, not just the most recent one so will
continue with both patches.
