pg_dump and sequences - RFC

It recently came to my attention that pg_dump dumps 'CREATE SEQUENCE' and
'SELECT NEXTVAL' commands for both data-only and schema-only output. This
results in problems for users who do the two in separate steps, and seems a
little odd.

Also, I'd be interested to know what the purpose of 'SELECT NEXTVAL' is?

My inclinations is do do the following:

- Issue 'CREATE SEQUENCE...Initial Value 1...' in OID order
- Issue 'SELECT SETVAL...' at end of data load.

This means that a schema-only restore will hgave all sequences set up with
initial value = 1, and a data-only restore will have sequences set
'correctly'.

Does this sound reasonable?
