Add pgstat test for reset of dead/live counters with table truncation A patch has been proposed to refactor the table-level statistics to treat the non-transactional and transactional parts as two separate entities, in the scope of a larger piece of work to introduce transactional flushes.
This commit adds a test for a pattern that has proved to be problematic while splitting the relation stats data, and where we had no coverage yet: an entry marked as truncdropped resets the live/dead counters in the flush callback, leaving any other data intact. The code path resetting the live/dead counters was covered, but nothing in the regression tests checked the stats views for it. Extracted from a larger patch by the same author.
