reinitialize a sequence?

hello,
played a bit around with the serial type....
wanted to adapt my already existing tables to this system...
dumped the DB, created the new tables, loaded old data in....

all works, until i try to insert something without specifying the id
field (that's the now sequential field). And the reason is that the
sequene is set to 1.....

is there a simple way to tell all sequences to take the max value +1 of
their respective tables? (a bit like the vacuum command?)

i tryed to set the value by hand, but did something wrong :D the command
didn't completed:
fibu=> update journal_id_seq set last_value=1187;
ERROR: You can't change sequence relation journal_id_seq

surely something real stupid again, but i never used sequences till
now... and there's no example in the docu.... (BTW would be nice if this
was addressed in the documentation)
