hello to everyone,
is a bit late for an italian, but after an long day debugging I had an
idea.
Why not introduce a special SQL command like
STORE WHERE [condition] FROM [table]
removing all data that meet the condition and storing them into another
database?
Then, if a query that needs the stored data is executed after such
command
the database joins the stored data into the result query.
This can keep the production database lightweight and fast.

DELETE ... RETURNING is useful for this kind of thing, sometimes. And
you could use it inside a function to go and do something with each
row returned, though that might not be very graceful for large numbers
of rows. The proposed syntax wouldn't actually work because it
doesn't specify where to put the data.
