@@ -168,6 +168,7 @@ typedef struct PgStat_TableCounts
PgStat_Counter t_tuples_updated;
PgStat_Counter t_tuples_deleted;
PgStat_Counter t_tuples_hot_updated;
+ PgStat_Counter t_tuples_newpage_updated;
bool t_truncdropped;

I have in the works something that's going to rename these fields to
not have the "t_" prefix anymore, to ease some global refactoring in
pgstatfuncs.c so as we have less repetitive code with the functions
that grab these counters. I don't think that's something you need to
name without the prefix here, just a FYI that this is going to be
immediately renamed ;)
