I just noticed an existing incoherency that I'm wondering about fixing as part of 0007 "pgstat: prepare APIs used by pgstatfuncs for shared memory stats." The SQL functions to reset function and relation stats pg_stat_reset_single_table_counters() and pg_stat_reset_single_function_counters() respectively both make use of pgstat_reset_single_counter(). Note that the SQL function uses plural "counters" (which makes sense, it resets all counters for that object), whereas the C function they call to perform the the reset uses singular. Similarly pg_stat_reset_slru(), pg_stat_reset_replication_slot(), pg_stat_reset_subscription_stats() SQL function use pgstat_reset_subscription_counter(), pgstat_reset_replslot_counter() and pgstat_reset_subscription_counter() to reset either the stats for one or all SLRUs/slots. This is relevant for the commit mentioned above because it separates the functions to reset the stats for one slru / slot / sub from the function to reset all slrus / slots / subs. Going with the existing naming I'd just named them pgstat_reset_*_counters(). But that doesn't really make sense. If it were just existing code I'd just not touch this for now. But because the patch introduces further functions, I'd rather not introducing more weird function names. I'd go for pgstat_reset_slru_counter() -> pgstat_reset_slru() pgstat_reset_subscription_counter() -> pgstat_reset_subscription() pgstat_reset_subscription_counters() -> pgstat_reset_all_subscriptions() pgstat_reset_replslot_counter() -> pgstat_reset_replslot() pgstat_reset_replslot_counters() -> pgstat_reset_all_replslots() We could leave out the _all_ and just use plural too, but I think it's a bit nicer with _all_ in there. Not quite sure what to do with pgstat_reset_single_counter(). I'd either go for the minimal pgstat_reset_single_counters() or pgstat_reset_one()? Greetings, Andres Freund
