E.226. Sortie 6.0


Date de sortie


A dump/restore is required for those wishing to migrate data from previous releases of PostgreSQL™.

E.226.1. Migration from version 1.09 to version 6.0

This migration requires a complete dump of the 1.09 database and a restore of the database in 6.0.

E.226.2. Migration from pre-1.09 to version 6.0

Those migrating from earlier 1.* releases should first upgrade to 1.09 because the COPY output format was improved from the 1.02 release.
