I think it is bit difficult because pg_replication_origin_drop() has PID in the
ERROR message. Also, this patch prevents first process resets the origin, i.e.,
the exact same situation won't happen anymore. Not fixed.

The step has already existed, see below.

```
step s0_reset: SELECT pg_replication_origin_session_reset();
ERROR:  cannot reset replication origin with ID 1 because it is still in use by other processes
step s1_reset: SELECT pg_replication_origin_session_reset();
pg_replication_origin_session_reset

```

Others are corrected and adjusted by me, see the attached.
0001 and 0002 are combined because no one claimed them.
