You said you were running 8.0 but "nextval('job_primary_seq'::regclass)"
suggests 8.1. What does "SELECT version()" show?
What are the output of the following?
EXPLAIN ANALYZE SELECT "primary" FROM job WHERE "primary" = 370;
EXPLAIN ANALYZE DELETE FROM job WHERE "primary" = 370;
If these commands use index or bitmap index scans, do you get
different results if you execute the following commands and then
try the delete again?
SET enable_indexscan TO off;
SET enable_bitmapscan TO off;
