The buildfarm has backfired with the ABI compliance check, which has
made me double-check for some extension code where the API change
would matter, based on this list:
https://wiki.postgresql.org/wiki/CustomCumulativeStats

And I did see one spot here, where there is a
pgstat_custom_drop_entry() that maps to a definition of
pgstat_drop_entry():
https://github.com/pganalyze/pg_stat_plans

I'll go file a ticket.
