There have been a few threads on the behavior of WAL archiving, after a
standby server is promoted [1] [2]. In short, it doesn't work as you
might expect. The standby will start archiving after it's promoted, but
it will not archive files that were replicated from the old master via
streaming
for some reasons, these old WALs were forgotten by the
restartpoint mechanism when they should have been recylced/deleted.

To test WAL replay, I often set up a master-standby system with

However, the regression suite doesn't generate all WAL record types. I
spent some time looking at the lcov report (make coverage-html), and
