This partially reverts 68cb5af, as using archiving to enforce the rename of the last partial segment of the old timeline at promotion to use .partial as suffix is impacting the tests when it does switchovers. As showed by the logs gathered by the CI in the tests that failed, a new standby may fail to find the WAL segment it needs to follow a promoted instance with its timeline jump, as it got renamed to .partial. This problem would manifest as a run timeout with 009_twophase.pl, as the new standby repeatedly requests a segment from the promoted primary that it would not find.
