A Modern PostgreSQL Client for the Mac. #macos, #database, #database-service, #apps 6 people use Postico. Yes I use something else. People that stacked Postico. Python 3 is supported if it's version 3.1 or later; but see Section 45.1 when using Python 3. Since PL/Python will be a shared library, the libpython library must be a shared library also on most platforms. This is not the case in a default Python installation built from source, but a shared library is available in many operating system.

Postgres.app
To connect to Postgres.app, you can leave all fields blank.
- Host: localhost
- Port: 5432
- User: your user name
- Password: blank
- Database: your user name
See also: Installing Postgres.app
EnterpriseDB
To connect to a PostgreSQL server installed with the graphical installer from EnterpriseDB, click the “New Favorite” button and provide the following parameters:
- Host: localhost
- Port: 5432 (can be changed during installation)
- User: postgres
- Password: selected during installation
- Database: postgres
MacPorts
To connect to a PostgreSQL server installed with MacPorts, use the following parameters:
- Host: localhost
- Port: 5432
- User: postgres
- Password: blank
- Database: postgres
Firewalls & Internet Filters
Some protection products interfere with TCP connections. For example, a product named X3 Protect has been known to block connection attempts to local PostgreSQL servers. If you are having trouble connecting to a local PostgreSQL server, try disabling your firewall, or add an exception for port 5432.
“Resolving localhost failed”
This error message usually appears when there is a problem with the /etc/hosts file. Make sure there is an entry for localhost. As a workaround, you can also type “127.0.0.1” into the host field instead of “localhost”.
TCP vs. Socket connections
There are two ways to connect to a local PostgreSQL server:
- Using a TCP connection (localhost, 127.0.0.1, ::1)
- Using a Unix socket connection (/tmp/.s.PGSQL)
Postico always uses TCP connections. Postico can't use socket connections because sandboxed apps are not allowed to access unix sockets outside their sandbox.
By default, PostgreSQL is always configured to listen for TCP connections on localhost, so that should not be a problem unless you explicitly disabled TCP connections.
Postgres.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.
Postgres.app 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.
Postgres.app can install minor updates automatically, so you get bugfixes as soon as possible.
Installing Postgres.app
- Download ➜ Move to Applications folder ➜ Double ClickIf you don't move Postgres.app 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:
Host | localhost |
Port | 5432 |
User | your system user name |
Database | same as user |
Password | none |
Connection URL | postgresql://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 Postgres.app.
Graphical Clients
Postgres.app 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 Postgres.app, 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:
Django
In your settings.py, add an entry to your DATABASES setting:
Flask
When using the Flask-SQLAlchemy extension you can add to your application code:
SQLAlchemy
To install the pg gem, make sure you have set up your $PATH correctly (see Command-Line Tools), then execute the following command:
Rails
In config/database.yml, use the following settings:
Sinatra
In config.ru or your application code:
ActiveRecord
Install the activerecord gem and require 'active_record', and establish a database connection:
DataMapper
Install and require the datamapper and do_postgres gems, and create a database connection:

Sequel
Edgeview 2 24 – cutting edge image viewer. Install and require the sequel gem, and create a database connection:
- Download and install the PostgreSQL JDBC driver
- 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.

Support
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 Postgres.app that is not answered by the Postgres.app documentation,you can ask @PostgresApp on Twitter, or open an issue on GitHub.
When reporting bugs, let us know which version of Postgres.app & macOS you are using, and be sure to include detailed error messages, even if your issue seems similar to another one.
