Re: [Postgres-xc-developers] GTM standby bugs

[Koichi S. <koi...@gm...>]

I reviewed patches and tested them.   The patch look reasonable and does
not influence the regression.    Because these patches are submitted four
days ago and everybody had good amount of time to think about it, I think
it safe to commit it now.

Please respond to me in an hour if you have any further inputs to this.
