OK. Given the discussion of 'select nextval', do you know if 'select
setval' will set the is_called flag? If not should I:

Issue 'CREATE SEQUENCE...Initial Value <MINVAL>...' in OID order

if (is_called was set AND we've loaded any data) then

Issue 'SELECT NEXTVAL...' at end of data load, and *before* setval.
Issue 'SELECT SETVAL...' at end of data load.

endif
