Your best bet would be to install Slony-I. One of the main design goals for Slony is to allow interruption-free upgrades. Basically, you can set up the new database server (using a different port or whatever), and install/configure Slony. Slony will then keep your two database in sync. Then you can switch over to the new database whenever suits you: http://www.slony.info -- Bill Moran http://www.potentialtech.com http://people.collaborativefusion.com/~wmoran/ -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
