TODO items..

I saw the following in the TODO list. I am currently trying to work on them.
I could not understand clearly what needs to be done. Can anybody give me
the details for the following so that I can work on?

clients-psql
=========
1. Have psql show current values for a sequence
2. Fix psql's display of schema information (Neil)

Please explain me the current feature that is supported and  expected 
out of it.

Thanks
Dhanaraj
