Re: nextval on insert by arbitrary sequence

Have you looked at the serial type?

This type creates an explicity sequence with a predictable name:
tblname_rowname_seq

and has a default value that selects the next val from that sequence.
You can get the value of the most recently inserted row in your session 
with
CurrVal('tblname_rowname_seq')

Hope this helps :)
