Обсуждение: How to use pg_upgrade for beta versions
It has been recommended to pg_upgrade from 9.4 beta 1 to 2: http://www.postgresql.org/message-id/20e710fd3e4790ee1051aa1e107d3708@postgresql.org How do I that on the Ubuntu 14.04.1 PPA? http://www.postgresql.org/download/linux/ubuntu/ Upgrading directly is not possible: $ sudo apt-get dist-upgrade Preparing to unpack .../postgresql-9.4_9.4~beta2-1.pgdg14.04+1_amd64.deb ... ERROR: The database format changed between beta 1 and 2.

In any event I do not remember pg_upgrade being integrated into the apt-get process.

It would seem you would want to do a straight install of 9.4beta2 where the package manager sets up a separate instance for it and then use pg_upgrade to move the data from beta1 to beta2. Otherwise you could go the dump/restore route. > -- Adrian Klaver adrian.klaver@aklaver.com

Yeah, it seems the packagers should be using pg_upgrade for this, as I think they already use it for major release upgrades. Adrian is right, though, that you might just need to run pg_upgrade manually. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + Everyone has their own god. +

I don't know if it handles beta upgrades though. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
