Unknown values in int8 fields?

Hi Chris,

When I load records with copy <table> from ... And one of the fields (last
one) is left empty, I want the default of nextval('sequence_table') to kick
in - but it doesn't.
Now, the field with a unique index on it stays blank. No big deal if I could
go and say 'update rate set recno = nextval('sequence_rate') where recno = 0
- but it's not that easy as the recno is not 0 but - hmm what? What can I
check for? I tried '?' and ? And 0 and ... And ... And ... But nothing works
... Now what?

Best regards
Chris
