Thanks for the review. I've looked a bit more at the other paths
handling dropped entries and they should be fine, created a TAP test
that's able to check the scenario sent by Anton with a background psql
session and some shutdown checks (critical part is the generation of
the pgstats file), then applied the fix down to v15.
