Going by "Since those rows are inserted by hand, they will be lost when the table will be reimported.", I just imagined there must be some sort of TRUNCATE + INSERT/COPY operation going on, in which case there would be a good upside of not having to perform a DELETE of all automatic records instead of the TRUNCATE. I could be wrong to assume that though. -- David Rowley http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
