Risky--even if it happened to work today on your OS versions, there's no guarantee that it will continue to work. PostgreSQL uses "native"ish types on each OS, so there's a possibility of files on one OS not working on another. I have been copying down from Linux to Mac OS for quite a while for local dev work, but Linux/BSD are closer than Windows/BSD and if it stops working one day I lose nothing. > On Sep 5, 2017, at 7:32 AM, Andrea Bonomelli <andrea@xxxxxxxxxxxxxxxx> wrote: > > Hello > > Is it possible to install postgreSQL on a thunderbolt drive connected on MacOS and then plug the drive on Windows server and still be able to connect to it? > > I'm not sure if there's a clumsy procedure for it or not... > > Thanks! > > -- > > Andrea Bonomelli > OKAY STUDIO > > +44 207 127 0764 > > okaystudio.co.uk / twitter / facebook > > > This transmission is confidential and may be privileged.
