If you intend to upgrade your PostgreSQL installation, you may need to
|
|
perform a dump-and-restore to move your current databases into the newer
|
|
PostgreSQL installation. Please dump your databases *prior* to installing
|
|
the new PostgreSQL.
|
|
|
|
Please see the Backup and Restore section of the PostgreSQL Administrator's
|
|
Guide (databases/postgresql-docs) for complete information on how to
|
|
perform the databases dump.
