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.
