Nope, I tried doing an
UPDATE name-of-sequence SET last_value=200
and I got an error about not being able to update the sequence. However,
always being one to hit a brick until it cracks, I then tried:
DROP name-of-sequence;
CREATE name-of-sequence START 1000;
This seemed to work! When I then INSERTed a new tuple, the attribute defined
as SERIAL actually got the value of 1000. Curious, but nice.
