Rule uses wrong value

(I thought I posted this yesterday from Google Groups, but it doesn't
appear to have "taken".)

I'm having a problem with a rule designed to log new rows inserted into
one table. The base table is very volatile; rows are inserted from
various places, including both application code and triggers. Then they
are read out by another application (the table is used as a job queue)
and deleted. My rule attempts to re-record the rows in another table for
audit and debug purposes.

Here's the important bits of the base table:

Table "public.job_queue"
Column  |Type    |Modifiers

--------+--------+------------------
job_id  |integer |not null default
                   nextval('"job_queue_job_id_seq"'::text)
...

The rule looks like this:

rul_job_queue_trace_log AS
ON INSERT TO job_queue
DO INSERT INTO job_queue_trace (job_id, ...)
VALUES (new.job_id, ...)

It appears that the rule is inserting the row copies into
job_queue_trace with a job_id value that is one higher than the job_id
from the original row. Almost as though it was re-evaluating the
sequence ...
