Am I right that on PostgreSQL upgrade to new major version (e.g. from 
9.0 to 9.1) I'll loose my backups (base backups and wal files will be 
useless)? So to go to past after DB upgrade  I had to install old 
version(9.0), recover data and then upgrade DBMS software...
What is the preferred way to deal with this issue?
Best regards,
