It's been discussed before. One idea is to declare tables without
logging. The idea being that during recovery those tables and related
indexes are simply truncated. No foreign keys allowed. Obviously they
will not be saved via PITR either.
Put another way, the table structure is saved in WAL, but the data
isn't.
Have a ncie day,
