I uninstalled 9.2 before installing 9.3.1.0. The app is called Postgres93, it is version 9.3.1.0 I downloaded the latest pgAdmin, it is pgAdmin3 version 1.18.1
I have a database "MiniServer" which is supposed to use postgres as its Maintenance database. But there is no such database. Perhaps it can't find the DBs that were there? pg_upgrade requires pg_upgrade -b oldbindir -B newbindir -d olddatadir -D newdatadir [option...] but I'm not sure what the 'old' values should be (since I uninstalled 9.2 - maybe I shouldn't have?) In my /Library/PostgreSQL/9.2/data/global I see 42 files fom 8K to 25K in size, most created last March - my data must be there. So that may be telling me to create an empty folder, /Library/PostgreSQL/9.3/ In my Postgres93 bundle there's a Contents/MacOS/postgres, a small unix executable. Is that the binary? But again there's no binary for 9.2. I was rolling along with 9.2 getting lots of good work done via Eclipse/JDBC. But now I'm stuck. Sorry for being so dense. But I've never been afraid to ask questions. The answers I get increase my understanding of whatever the topic is. Thanks in advance for helping a tyro. - Bob
