c186ba13 has fixed an issue related to the updates of the minimum recovery LSN across multiple processes on standbys, but we never really had a test case able to reliably check its logic. This commit introduces a new test case to close the gap, and is designed to check the consistency of data based on the minimum recovery point set by either the startup process or the checkpointer for both an offline cluster (by looking at the on-disk page headers) and an online cluster (using pageinspect). Note that with c186ba13 reverted, this test fails badly for both the online and offline cases, as designed.
