Organizing Postgres Databases Is there a way in pgAdmin to organize Postgres databases into "folders" or groups? Each Django project I'm creating has it's own Postgres database, and I would like to find a way to organize them.

I asked this question on StackOverflow (https://stackoverflow.com/questions/22727629/organizing-postgres-databases), and my question was "put on hold" because it was off topic.

On StackOverflow, Erwin Brandstetter suggested I create a new Server Group and set the Group dialog box:



My question is: how to create new options for the "Group" dropdown box? When I use pgAdmin3 command "Add Server" on my MacBook Pro, I only see one option under "Group" called "Servers".

Do I need to create a new "Database Cluster"? I found this command in the Postgres Documentation in Section 17.2:

$ initdb -D /usr/local/pgsql/data


On my MacBook Pro, my default databases are located at /usr/local/var/postgres/base and /usr/local/var/postgres/global.

Should I create a new directory, such as /usr/local/var/postgres2, and then execute a command like this?

$ initdb -D /usr/local/var/postgres2
Just type it into the "Group" field. Besides the listed options you can type a new group name freely.

It's a setting of pgAdmin, completely independent of the database itself and not stored in the database.

The handling is flexible, but renaming a bunch of "servers" can get tedious.

As to your comment: I repeat what I already wrote in my last answer: 


  Basically, each connection allows access to a whole database cluster


But if you follow my instructions over there, you connect to the right database automatically. I suggest, you read the manual about Managing Databases for basic understanding.
