You can query: select * from sequence_name;

I honestly doubt such a feature would be added to the system catalog,
but it certainly might be a nice thing to output to the logs. You might
want to add your request to the wiki so it doesn't get lost:

One thing you can do at the moment is track how close the sequence is
getting near its maxvalue, and thus have an idea of when it is about
to cycle. The check_postgres program can do this for you:
