All my previous version upgrades were performed by running pg_dumpall in the older version followed by running 'pgsql -f ...' to install the dumped .sql file, usually because the upgrade jumped several versions. Now I'd like to try the available postgres commands. The older version is installed in /var/lib/pgsql/9.5/data and I just initiated the new version in /var/lib/pgsql/9.6/data. The earlier version is currently running. Is pg_upgrade the recommended way to upgrade from one minor version to the next? The 9.5 manual recommends this approach for _major_ upgrades (e.g., 8.4.7 to 9.6.1), but not for _minor_ upgrades (e.g., 9.0.1 to 9.0.4). That's a first digit upgrade and a third digit upgrade. Since 9.5.4 to 9.6.1 is a second digit upgrade I suppose it's semi-major, but in which upgrade camp does it belong? The command is: pg_upgrade -b oldbindir -B newbindir -d olddatadir -D newdatadir and I don't know where to find -b and -B. On my Slackware-14.1 server I have /usr/bin/postgres and assume it is for the 9.5 release since that's running and the 9.6 release is initiated but not invoked. The data directories are easy but where do I look for the two bindirs?
Assuming the bindirs are in your $PATH: aklaver@panda:~> whereis -f pg_ctl pg_ctl: /usr/local/pgsql/bin/pg_ctl /usr/local/pgsql94/bin/pg_ctl Even if only one is the $PATH: aklaver@panda:~> whereis -f pg_ctl pg_ctl: /usr/local/pgsql/bin/pg_ctl you can usually figure out where the other is.
