This is a quick guide for installing PostgreSQL (Postgres for short) on a Mac with Homebrew, and starting and stopping it with Homebrew Services. If you're working on a Ruby on Rails project that requires Postgres, this tutorial will get you up and running in no time.

The easiest way to install Homebrew, Postgres, and all the othertools necessary for Ruby on Rails development, is to run my free script that will set everything up for you.

Sep 30, 2019 $ brew install postgresql This install the command line console (psql) as well as the server, if you'd like to create your own databases locally. Run the following to start the server and login to it (it basically sets up a single 'admin' user with your username, so that's who you'll be logged in as.

Run the following to start the server and login to it (it basically sets up a single 'admin' user with your username, so that's who you'll be logged in as. $ brew services start postgresql $ psql postgres.
  2. To migrate existing data from a previous major version of PostgreSQL run: brew postgresql-upgrade-database This formula has created a default database cluster with: initdb -locale=C -E UTF-8 $(brew -prefix)/var/postgres For more details, read: https://www.postgresql.org/docs/13/app-initdb.html.
  3. Install PostgreSQL brew install postgresql Start PostgreSQL brew services start postgresql Start PostgreSQL shell psql postgres Create User in PostgreSQL CREATE ROLE “express-mvp-dbuser” WITH LOGIN PASSWORD ‘123.456’.
  4. Once Homebrew is installed, you can install PostgreSQL by issuing the following commands in your terminal: $ brew update $ brew doctor $ brew install postgres The first two commands are used to update Homebrew and report any potential issues (if necessary). Then, of course, brew install postgres is the one-line command for installing PostgreSQL.

If you prefer to do things manually and hope for the best, follow the steps below.

Step 1: Install Homebrew

Follow the instructions on their site.

Step 2: Update Homebrew

Before you install anything with Homebrew, you should always make sure it's up to date and that it's healthy:

Step 3: Install Postgres

When you install Postgres, Homebrew will provide useful information in your Terminal that you should read. Homebrew also helpfully creates a default database cluster. You can confirm that if you see the following output:

Step 5: Start the Postgres service

At this point, you should be all set to run the Rails commands to create and use the database in your app.

To stop Postgres:

After upgrading a few programs including postgres when starting a new project, I ran into an issue. I already had some postgres databases from older projects and I couldn't start postgres (and create my new database).

To install postgres with brew I used:

Brew Services Start Postgresql エラー

To see if postgres is running I can type:

Then the funny thing was when I tried to start the service:

Great! So it's running! But no..

To see what is the issue, let's look at the logs:

And there was the issue.
All I had to do to fix this was to run this command:

Then let's start it postgres:

Now I can see that I have two postgres services with the two different versions. I can create my new updated database. Also the good thing is that I didn't lose any data from previous project and I can run the service with version 12 if I ever need it.
