The question is: how complex is the data you need to
extract? I guess where I was heading was to run a
select with the interval Scott described from psql into
a file, and then copy-from that into the analysis database.

However, if the structure is more complex, if you needed
to join tables, the parsing of a dump-file may be an option,
even though (always retaining a weeks worth) might make
that into quite some overhead.
