Re: pg_stat_replication vs StandbyReplyMessage

Hello hackers,

Still need to solve this topic?

/messages/by-id/CABUevEwA=AFWXr-7cCpZ9MDdxHL2wFGsxFiB6uyFDTOhRudGrA@mail.gmail.com

I saw this topic in todo list,
so I implemented simple patch.

/messages/by-id/1657809367.407321.1533027417725.JavaMail.jboss@ep2ml404

If it was not necessary, please let me know.

Feedback and suggestion will be very welcome.
Thanks!

Best regards,
Myungkyu, Lim

The pg_stat_replication view exposes all the fields in
StandbyReplyMessage *except* for the timestamp when the message was
generated. On an active system this is not all that interesting, but
on a mostly idle system that allows the monitoring to react faster
than the timeout that actually kicks the other end off - and could be
useful in manual debugging scenarios. Any particular reason why this
was not exposed as it's own column?

Did this ever get done? I don't think so, though everyone wanted it.

Nope, it wasn't done. Should probably do that for 9.3 (since adding a
field to pg_stat_replication will cause initdb, so we can't really do
it for 9.2 unless it was really critical - and it's not).

OK, TODO added:

Add entry creation timestamp column to pg_stat_replication
