Sequence Bug in Postgres 9.2.4 ?

I'm creating a table in postgres 9.2.4 with a sequence for the primary key. The sequence that gets created has a very long name (>31 chars). I need to alter it, but can't. Can anyone think of a work around?

<code>
--I create the table like this

CREATE TABLE "userreg_userregformcompleted" (
    "regFormNumber" serial NOT NULL PRIMARY KEY,
);

---

-- Here it is and I can find it any other way with this name

\ds:

                             List of relations
 Schema |                      Name                      |   Type   | Owner
--------+------------------------------------------------+----------+-------
 public | userreg_userregformcompleted_regFormNumber_seq | sequence | als

----

-- but I can't access it. If I change the name in a gui it works.

alsdb=# alter sequence userreg_userregformcompleted_regFormNumber_seq restart with 10;

ERROR:  relation "userreg_userregformcompleted_regformnumber_seq" does not exist
