Postgres For Mac Os

Download the Mac OSX Postgres package one click installer; run the installer, the installer tells you it changed a system file. Restart your Mac; run the installer a second time, Postgres gets installed. Remember the password you entered. If you don't change anything else, the default user should be called 'postgres'. Oct 24, 2016 Postico is a modern Postgres client for OSX, built by the same developer who built (mentioned above). It is free, but you can buy a license to unlock additional power features. This is the GUI that I use to manage Postgres because it is built specifically for Mac and has a beautiful, very easy to use (but powerful) UI. PostgreSQL is a robust, scalable and well supported Open Source database engine. This packaging installs it into Mac OS sensitive locations and adds some limited graphical management tools, with. If you have more trouble, though, the easiest (and recommended by postgresql) way to install postgresql on Mac OS X is via the GUI installer provided by EnterpriseDB. It even handles installing multiple versions quite nicely. is a simple, native macOS app that runs in the menubar without the need of an installer. Open the app, and you have a PostgreSQL server ready and awaiting new connections. Close the app, and the server shuts down. PostgreSQL can also be installed on macOS using Homebrew. Please see the Homebrew documentation.


Postgres is a powerful and free object-relational database management system. It has gained a lot of momentum since its introduction in 1995 because of its robustness and powerful features it ships with out of the box. In this article, we’ll walk through the process of installing a Postgres database on a Mac OS X machine and set it up for Ruby on Rails development.

Install Postgres Database with Homebrew

Homebrew is a popular package manager for OS X. To install Postgres with Homebrew, follow the steps below:

Postgresql For Mac Os 10.10

The first thing to do is install Homebrew if you haven’t done so already. Homebrew site has a simple command that you have to paste in your terminal to do so. Make sure to accept the command line developer tools installation if prompted.

Next, run brew install postgres to install Postgres. It might take a little while to compile and install. After compilation is done, it’ll give you some instructions to finish setting it up.

The database will be initialized during installation, so there isn’t a need to run initdb to finish installation of Postgres via Homebrew. Near the end of the installation instructions you should see mention of the command brew services.

If you don’t already have brew services installed. It may be installed withthis command:

And then you can run the following command to start Postgres as a background service:

Postgres will also restart automatically at login after you have run the command above.
Once Postgres has started, we can use brew services to stop it manually:

Or we can also use brew services to restart Postgres:

Now you should have PostgreSQL all set up.

Set Up Postgres to Work with a Rails App

First, install the pg gem:

Make sure you include the pg gem in your Gemfile, and run

Now, set up your config/database.yml file to point to your Posgres database.

Let’s create the development and test databases:

Now you can run pending migrations, if there are any. is a full-featured PostgreSQL installation packaged as a standard Mac app.It includes everything you need to get started:we’ve even included popular extensions like PostGIS for geo data and plv8 for JavaScript. has a beautiful user interface and a convenient menu bar item.You never need to touch the command line to use it – but of course we do include all the necessary command line tools and header files for advanced users. can install minor updates automatically, so you get bugfixes as soon as possible.


  • Download ➜ Move to Applications folder ➜ Double Click

    If you don't move to the Applications folder, you will see a warning about an unidentified developer and won't be able to open it.

  • Click 'Initialize' to create a new server

  • Configure your $PATH to use the included command line tools (optional):

Done! You now have a PostgreSQL server running on your Mac with these default settings:

Useryour system user name
Databasesame as user
Connection URLpostgresql://localhost

To connect with psql, double click a database. To connect directly from the command line, type psql. If you’d rather use a graphical client, see below.

Mac Os Versions

NOTE: These instructions assume that you’ve never installed PostgreSQL on your Mac before.If you have previously installed PostgreSQL using homebrew, MacPorts, the EnterpriseDB installer, consider removing other PostgreSQL installations first.We also have instructions for upgrading from older versions of

Graphical Clients includes psql, a versatile command line client for PostgreSQL.But it’s not the only option; there are plenty of great graphical clients available for PostgreSQL.Two popular tools are:

pgAdmin 4 is a feature rich open source PostgreSQL client.It has support for almost every feature in PostgreSQL.The only downside is that the cross-plattform UI really doesn’t live up to the expectations of a native Mac app.

Postico on the other hand, is a very modern Mac app.It’s made by the same people that maintain, and we think you’ll like it! We put a lot of effort into making it a joy to use.However, it doesn’t have the extensive feature set of pgAdmin, and it’s a commercial app rather than open source.

Aside from those two options, there are a lot more to choose from! Check the documentation for a list of amazing Mac apps for PostgreSQL.

How to connect

After your PostgreSQL server is up and running, you’ll probably want to connect to it from your application.Here’s how to connect to PostgreSQL from popular programming languages and frameworks:

Mac os high sierra

To connect from PHP, make sure that it supports PostgreSQL. The version included with macOS doesn't support PostgreSQL. We recommend MAMP for an easy way to install a current version of PHP that works.

You can use PDO (object oriented):

Or the pg_connect() functions (procedural):


To connect to a PostgreSQL server with Python, please first install the psycopg2 library:


In your, add an entry to your DATABASES setting:

Postgres macos terminal


When using the Flask-SQLAlchemy extension you can add to your application code:



To install the pg gem, make sure you have set up your $PATH correctly (see Command-Line Tools), then execute the following command:


In config/database.yml, use the following settings:


In or your application code:


Install the activerecord gem and require 'active_record', and establish a database connection:


Install and require the datamapper and do_postgres gems, and create a database connection:


Install and require the sequel gem, and create a database connection:

  1. Download and install the PostgreSQL JDBC driver
  2. Connect to the JDBC URL jdbc:postgresql://localhost

For more information see the official PostgreSQL JDBC documentation.


libpq is the native C client library for connecting to PostgreSQL. It's really easy to use:

Now compile the file with clang and run it:


You can just use the C API in Swift! First include libpq in your bridging header:

Then make sure to link with libpq.

On iOS, you'll need to build libpq yourself.

On macOS you can use the system provided libpq (does not support SSL) or use libpq provided by by adding the following build settings:

Mac Install Postgresql

Other Linker Flags-lpq
Header Search Paths/Applications/
Library Search Paths/Applications/

Now you can use the libpq C library to connect to PostgreSQL:


We have a list of common problems in the troubleshooting section in the documentation.

For general questions concerning PostgreSQL, have a look at the official PostgreSQL documentation.

If you have a question concerning that is not answered by the documentation,you can ask @PostgresApp on Twitter, or open an issue on GitHub.

When reporting bugs, let us know which version of & macOS you are using, and be sure to include detailed error messages, even if your issue seems similar to another one.
