Getting rid of postgres output

["Nicola Mauri" <Nicola.Mauri@xxxxxxx>]

I scheduled a dump between two databases,
via network:
 
pg_dump --clean -U postgres mydb  |
psql -q -h remote_host -d mydb -U postgres

I'd like to have no output being generated,
unless an error condition occurs, so that crond will email me only when
something goes really wrong.
Unfortunately I'm getting this output:

 setval 
--------
 551776
(1 row)

 setval 
--------
 340537
(1 row)

 setval 
--------
  10411
(1 row)

and so on........
It seems to be related to some sequences
recently added to the database. Actually we are getting one 'setval' line
for each sequence defined.

Does anyone know how to get rid of this
output?
Simply redirecting output is not a great
idea, as we may loose some precious error messages too; so I think we should
prevent this messages to being generate at all.
(Postgres 8.1.3 on RHEL4)

Thank You!
