If your 9.6 database does indeed contain your databases, then something must have done the pg_upgrade for you. Perhaps the slackware package script does something like that, No, it only builds the package. I manually install it and run initdb. What I think what happened is that you are using the new pg 9.6 psql binary to list the databases in your old 9.5 cluster. Not only list them, but access them from the command line. This is what I'm trying to understand. Regardless, I'll stop the running postgres, run pg_upgrade, then start it from the /9.6/data/ directory.

Initdb doesn't do that. If your 9.6 database does indeed contain your databases, then something must have done the pg_upgrade for you. Perhaps the slackware package script does something like that, but that would cause problems for people who do _not_ want to migrate their databases, so I doubt that's what happened.

After installing and initiating 9.6.1 that's reported as the current running version, yet I've not yet migrated the cluster from 9.5.4 to 9.6.1. Last week, after a kernel upgrade, I rebooted the system and re-started postgres pointing to the 9.5/data/ directory. When I enter the command 'psql -l' I see all the databases and assumed they running on 9.5.4. But that's not the case, is it? If 9.6.1 is currently running after running initdb, and I can access my databases, what does pg_upgrade do that's necessary?
