that *could be* the reason why it does not start!

is there any postgres or psql executable around?
I suspect the upgrade did nuke everything was not installed by apple.

Do you mean is there a data directory under postgres user home
directory? Can you run pg_ctl to start the cluster from within such
directory?

Any chance you can understand if data under the postgres user has the
size you expect the database to have?
I'm not a mac user, but I suspect the upgrade destroyed your installation.

Hi Michael,
I use PostgresApp on my Mac, and it has worked very nicely for me. It’s a very no-fuss installation. You should have an
appin our Applications folder called Postgres. Start that, and the Postgres server will be running. There’s a little
elephantin my menu bar that I can click on that shows me what databases are available. I can set it to start the server
automaticallywhen I log in. If you don’t have an app called Postgres or it doesn’t run when you click it, I’d say your
installationis damaged. If you can nuke it and start over, that’d be what I’d try. Start by dragging the app to the
trashand reinstalling. That might fix things. 

FYI I modified my .zshrc to include this line to add Postgres’ client apps to my path:
export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/11/bin

That way I have easy access to psql, pg_config, etc.


Hope this helps,
Philip
