7.0.0 long name truncation problem

When the name of a sequence auto-generated from a SERIAL type would be
longer than 32 chars, it appears that "CREATE TABLE" uses a different
name truncation algorithm than "DROP SEQUENCE".  Example below.  Note
the difference between the following:

        'process_state_subscripti_id_seq'
        'process_state_subscription_id_s'

Might be fixed in 7.1, I dunno.  Can anyone confirm this is a problem?
