Обсуждение: FW: Upgrade to 8.3

I think I just made a huge error.  I just upgraded all of my systems and in
the process I just upgraded the data base from 8.1 to 8.3.  At least I think
it was 8.1.  Anyway the postmaster won't run and I can't backup the old
database without a hue effort.  Is there a way around this or do I have to
reinstall the old server and back it up and then install the new version?

Thanks

You have to install 8.1 again.  You don't need to change anything else
that you upgraded; it suffices to compile a 8.1 version from sources
(you need the same compilation options though)
