pg_dump from older version and pg_restore in newer - Mailing list pgsql-admin

Hi,

I am planning  a migration from 9.1.7 to 9.4.0.

On many threads I noticed that the recommendation is “Be sure to use pg_dump from the *new* version to take the dump from the old database.”

Is that a must?

Is there a chance that a restore using new version will fail because the dump was taken with *old* bin?

Regards
