You should not have to do anything special with the serial or the
sequence (including setting it to 6). Possible sources for for your
error: 1) you are resetting the sequence value to 6 when you already
have a row with that value for film_id in the table, or 2) could be the
message is coming from a triggered insert "downstream" from your initial
insert (see your server log). BTW, 7.0+ tells you *which* index caused
the problem.
