PostgreSQL version: 8.0.3-2
Operating system:   linux
Description:        records lost
Details:

i discovered records in my postgresql database missing every 6 - 8 months. i
supsect those not updated or amended are the ones that are gone, still
wondering the real reason behind ? i doubt is lack of vaccum as my
transactions are minnimal, inserting about 200 records each month and
updating about 1000 records each month.

this happens with previous versions of postgresql as well.
