Re: [BUG] pg_stat_statements and extended query protocol

Sorry about the delay in response about this.

I was thinking about this and it seems to me we can avoid
adding new fields to Estate. I think a better place to track
rows and calls is in the Instrumentation struct.

--- a/src/include/executor/instrument.h
+++ b/src/include/executor/instrument.h
@@ -88,6 +88,8 @@ typedef struct Instrumentation
        double          nfiltered2;             /* # of tuples removed by "other" quals */
        BufferUsage bufusage;           /* total buffer usage */
        WalUsage        walusage;               /* total WAL usage */
+       int64       calls;

 } Instrumentation; 


If this is more palatable, I can prepare the patch.

Thanks for your feedback.
