Previously none of our tests triggered recovery conflicts. The test is primarily motivated by needing tests for recovery conflict stats for shared memory based pgstats. But it's also a decent start for recovery conflict handling in general. The only type of recovery conflict not tested yet are rcovery deadlock conflicts. By configuring log_recovery_conflict_waits the test adds some very minimal testing for that path as well.
