Not really - if you don't use the sequence it keeps its value. If you look at
pg_dump it issues an explicit setval() after a copy.
I'm not sure you can even work around it with a BEFORE trigger to check and
update the sequence, the nextval() call will probably be processed before the
trigger gets called (haven't checked). In any case, performance would be a
bit poor.
Is there any reason why you're supplying your own id values when you already
have a sequence?
