Postgres For Mac 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. Hi I am having trouble with postgres. I don't remember my postgres password and don't know how to change the password. I'm guessing I should change the md5 password settings I set a month ago, but I don't know how to find the file and open it using my terminal.

App 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.

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:


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:


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:

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.

License, PostgreSQL, and its extensions are released under the PostgreSQL License. The released binaries also include OpenSSL (OpenSSL License), PostGIS (GPLv2), and plv8 (3 clause BSD). is maintained by Jakob Egger. It was originally created by Mattt Thompson.

How To Install Postgresql On Mac

I started off programming Ruby on Rails applications on a Windows machine with an Ubuntu virtual machine running on top. But when I got my first job at a startup in California, I received a brand new shiny Macbook laptop.

I had never used a Mac before as I considered them overpriced relative to a desktop I could setup with Linux. But since that’s what I was given, that’s what I was used. One of the first things I had to do is figure out how to get Postgres up and running.

Eventually, I had to learn a good way to upgrade it as well. At my first job, I found that using Heroku’s Postgres app. At my next job, I used the homebrew package manager since that’s how our team used it.

So what follows is a mini-guide I put together on how to install postgresql on Mac as well as how to upgrade it with homebrew.

Now if you want to use Heroku’s Postgres app, it’s pretty easy and is a good alternative to homebrew.


Installing Postgres via Homebrew

This guide assumes that you have homebrew installed. If you don’t, you can find some instructions here.

Once you do that, all you have to do is issue the following command in your terminal:

$ brew install postgres

It should install the latest version of Postgres available via Homebrew. Pretty easy, right?

Upgrading Postgres via Homebrew

Ok, so let’s say you have to upgrade postgres. I had to follow these steps when I was upgrading to Postgres 9.6

Step 1 – Turn off Postgres

Postgresql tools for mac

The first step is to turn off the postgres service if it’s running in the background.

$ brew services stop postgresql

Step 2 – Upgrade

Next, we’ll use homebrew to upgrade it to the latest version.

$ brew update && brew upgrade postgresql

Step 3 – Switch

Finally, we’ll switch to the new version using the following command.

brew switch 9.6.1

You’ll see output like the following:

Step 4 – Ensuring Postgresql Starts Automatically At Startup (optional, but makes your life easier)

Now to ensure postgres starts automatically every time you start your Mac, you’ll need to do some extra setup.

I got the following setup from this blog post at tunnelsup.

Step A – You’ll need to setup LaunchAgents

Create the directory ~/Library/LaunchAgents if it doesn’t exist already.

Step B – Copy the plist file to ~/Library/LaunchAgents/

There’s a plist file that comes with the postgres install from homebrew.

When upgrading to 9.6.2, my plist was at /usr/local/Cellar/postgresql/9.6.2/homebrew.mxcl.postgresql.plist.

Copy the plist file to the LaunchAgents directory.

cp /usr/local/Cellar/postgresql/9.3.4/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/

Step C – Load launchctl

Now use launchctl to load the file using this command:

$ launchctl load -w homebrew.mxcl.postgresql.plist

You can also use a ruby gem called lunchy. I haven’t tried it but this blog post describes the process.

General Troubleshooting Tips And Useful Commands

The following command will show you if you have multiple versions of postgres installed.

$ brew info postgresql

This troubleshooting gist describes how to migrate data from one version of Postgres to another.

Troubleshooting Guide for Rails developers

This part gives you some common troubleshooting tips if you’re a Rails developer.

Since I primarily use Postgres for Ruby on Rails work, when I was upgrading I had a connection issue described below.

If you get a connection issue with a message such as the following:

Then try running this in your terminal:

If you see the above “FATAL…”, then issue the following commands:

WARNING: Before you issue the following commands, please make sure you back up your old local Postgres data if you need it. See the gist referenced in the General Troubleshooting Tips And Useful Commands section.

$ rm -rf /usr/local/var/postgres && initdb /usr/local/var/postgres -E utf8

Mac Os Install Postgresql

After running the above rm and initdb commands, you should see something similar to the following.


Postgresql Client For Mac

If you want to install Postgres via homebrew, follow the steps above. Make sure you backup your local data if you need it so you don’t accidentally erase something you need to keep. Other than that, let me know if you have any issues in the comments.
