It would have gotten things closer than it was before imo. We can't just rename the SQL functions, they're obviously exposed API. I'd like to remove the NULL -> all behaviour, but that should be discussed separately. I've hacked up the above, but after doing so I think I found a cleaner approach: I've introduced: pgstat_reset_of_kind(PgStat_Kind kind) which works for both fixed and variable numbered stats. That allows to remove pgstat_reset_subscription_counters(), pgstat_reset_replslot_counters(), pgstat_reset_shared_counters(). pgstat_reset(PgStat_Kind kind, Oid dboid, Oid objoid), which removes the need for pgstat_reset_subscription_counter(), pgstat_reset_single_counter(). pgstat_reset_replslot() is still needed, to do the name -> index lookup. That imo makes a lot more sense than requiring each variable-amount kind to have wrapper functions. > > Not quite sure what to do with pgstat_reset_single_counter().

What does "private" mean for you? They're exposed via pgstat.h not pgstat_internal.h. But not to SQL. Greetings, Andres Freund
