Fix assertion failure with latch wait in single-user mode LatchWaitSetPostmasterDeathPos, the latch event position for the postmaster death event, is initialized under IsUnderPostmaster. WaitLatch() considered it as a valid wait target in single-user mode (!IsUnderPostmaster), which was incorrect.
One code path found to fail with an assertion failure is a database drop in single-user mode while waiting in WaitForProcSignalBarrier() after the drop. Oversight in commit 84e5b2f07a5e.
