Is the server running locally and acceptingĬonnections on Unix domain socket "/var/lib/postgresql/.s.PGSQL.50432"? We must also pass the -new-options switch, because failure to do so results in the following: connection to database failed: could not connect to server: No such file or directory D, -new-datadir=DATADIR new cluster data directory d, -old-datadir=DATADIR old cluster data directory B, -new-bindir=BINDIR new cluster executable directory These inputs may be specified with "long names", to make them easier to visualize: -b, -old-bindir=BINDIR old cluster executable directory The "bin" directory for the new version (-B BINDIR) The "bin" directory for the old version (-b BINDIR) The data directory for the new cluster (-D DATADIR) The data directory for the old cluster (-d DATADIR) Pg_upgrade requires the following inputs ( pg_upgrade -help tells us this): When you run pg_upgrade, you must provide the following information: Move into his home directory (failure to do this will cause errors): cd ~ Switch to the dedicated PostgreSQL system user: su postgres Stop both server instances (this will stop both at the same time): sudo systemctl stop postgresql The installation output mentions this, at the bottom, but it's easy to overlook: Creating new cluster 9.6/main. Once installation succeeds, both versions will be running side-by-side, but on different ports. Install the new version (note that we specify the 9.6, explicitly): sudo apt install postgresql-9.6 On Ubuntu (and probably Debian), provided you are using the "official" repo, deb xenial-pgdg main, and provided you haven't changed the default filesystem paths or runtime options, the following procedure should do the job. The only "tricky" aspect of pg_upgrade is that failure to pass the correct value for an argument, or failure to be logged-in as the correct user or cd to the correct location before executing a command, may lead to cryptic error messages. In short, the process consists of installing the new version of PostgreSQL alongside the old version (e.g., 9.5 and 9.6), and then running the pg_upgrade binary, which is explained in (some) detail at. ( I didn't want to have to dump and restore data manually, so several of the other answers here were not viable.) I just upgraded PostgreSQL 9.5 to 9.6 on Ubuntu and thought I'd share my findings, as there are a couple of OS/package-specific nuances of which to be aware. Be sure to adjust the "old" and "new" directories accordingly, too. Update: This process is the same for upgrading 9.5 through at least 11.5 simply modify the commands to reflect versions 9.6 and 10, where 9.6 is the old version and 10 is the new version. I suggest you take some time to read the PostgreSQL documentation to understand exactly what you're doing in the above steps to minimize frustrations. Launchctl load ~/Library/LaunchAgents/Ĭheck /usr/local/var/postgres/server.log for details and to make sure the new server started properly.įinally, re-install the rails pg gem gem uninstall pg Move new data into place: cd /usr/local/var B the new PostgreSQL executable directory b the old PostgreSQL executable directory D the new database cluster configuration directory d the old database cluster configuration directory B /usr/local/Cellar/postgresql/10.1/bin/ b /usr/local/Cellar/postgresql/9.6.5/bin/ \ Run pg_upgrade (note: change bin version if you're upgrading from something other than below): pg_upgrade -v \ Initdb /usr/local/var/postgres10.1 -E utf8 INSTALLATION DIRECTORY: EXECUTABLE: /System/Library/Frameworks/amework/Versions/2.Assuming you've used home-brew to install and upgrade Postgres, you can perform the following steps.
