On slow machines, this test can take long enough to generate WAL that a time-based checkpoint occurs before the primary is stopped. If the checkpoint record is written to the tail WAL segment that the test later removes, a standby initialized from the resulting backup tries to read the missing checkpoint record and fails with a PANIC during startup. This caused the test to fail on buildfarm member skink. Fix this by setting checkpoint_timeout high enough to prevent unrelated checkpoints during the test. This follows the approach used by other recovery tests, such as 043_no_contrecord_switch.pl, that depend on a specific WAL layout. Backpatch to all supported versions.
