The only thing I can think of is another transaction preventing the autovacuum from removing the rows, but I can't reproduce it. What PostgreSQL version are you using? BTW take a look at this contrib module: http://www.postgresql.org/docs/9.1/static/pageinspect.html It allows looking directly on items on a data page like this: select * from heap_page_items(get_raw_page('test', 0)); Maybe that'll help you identify the problem.
