Guten Tag Keith, am Donnerstag, 23. Februar 2017 um 18:57 schrieben Sie: > You can go directly from 8.3 to 9.5. Just be sure and use the > pg_dump from 9.5 to generate the dump file from 8.3. Is there a specific reason for that? My current approach for upgrades was dumping the old database using the old pg_dump, uninstalling the old Postgres, installing the new one and restore from the old dump. That way I didn't accidently mix-up installations or use wrong tools or such. Did pg_dump have bugs in the past which resulted in pg_restore not being able to read the dumps?
