you are right. What it happens is that the batch importing process drops the schema and recreates it.  I would like some solution that is compatible with that.
I am sure partitioned tables will have an impact but on the other hand, it will solve the problem I have now without touching the legacy code.

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.
