This will work as long as you don't try to execute write queries on the slony master, because it's a standby node and, as such, can only execute read queries. Meaning I'm wondering why you would use such a scheme. > Regards, > > Ludovic Toinel > > -----Message d'origine----- > De : slony1-general-boun...@lists.slony.info [mailto: slony1-general-boun...@lists.slony.info] De la part de Andrew Sullivan > Envoyé : mardi 10 novembre 2015 12:26 > À : slony1-general@lists.slony.info > Objet : Re: [Slony1-general] Network connection from slaves to the master > > On Tue, Nov 10, 2015 at 09:51:29AM +0000, TOINEL, Ludovic wrote: > > The network allows only flows from master to slaves. > > > > Is there any option that I missed to do that ? > > Not really. In principle you could do this with the log shipping mode, but I don't recall whether doing that on the master was not possible or just a really bad idea.
