Re: Add a write_to_file member to PgStat_KindInfo

Hi,

Thanks for patch. I have tested both patches and they work as per design.

My +1 for v1, it is much cleaner approach and has properly named
functions whereas in v2 it is not.

Injection points is documented, if so, doc patch is missing.

Regards,
Yogesh
