It solves export and import as simple pg_dump -a  / psql -f   
operations, because the primary
keys are never repeatable, even in schemas on different machines where 
used sequence numbers
do not match.

Another approach, more involved and requiring more programming, is to 
export to
some structured document file, and to reimport it with a importer that 
parses the structured document
and issues sql insert statements. I was wondering if Carlos or someone 
has already / or is doing
this already.
