This is a postgres client that does auto-completion and syntax highlighting.

Quick Start

If you already know how to install python packages, then you can simply do:


$ pip install -U pgcli


$ sudo apt-get install pgcli # Only on Debian based Linux (e.g. Ubuntu, Mint, etc)
$ brew install pgcli  # Only on macOS

If you don't know how to install python packages, please check the
detailed instructions__.




$ pgcli [database_name]


$ pgcli postgresql://[user[:password]@][netloc][:port][/dbname]



$ pgcli local_database

$ pgcli postgres://amjith:pa$$


The pgcli is written using prompt_toolkit_.

  • Auto-completes as you type for SQL keywords as well as tables and
    columns in the database.
  • Syntax highlighting using Pygments.
  • Smart-completion (enabled by default) will suggest context-sensitive

    • SELECT * FROM <tab> will only show table names.
    • SELECT * FROM users WHERE <tab> will only show column names.
  • Primitive support for psql back-slash commands.

  • Pretty prints tabular data.
    Note: pgcli uses the tabulatepackage to pretty-print tables. This library does smart formatting
    of numbers, which can sometimes lead to unexpected output. See this issue
    for more details.

A config file is automatically created at ~/.config/pgcli/config at first launch.
See the file itself for a description of all available options.


If you're interested in contributing to this project, first of all I would like
to extend my heartfelt gratitude. I've written a small doc to describe how to
get this running in a development setup.

Please feel free to reach out to me if you need help.

Detailed Installation Instructions:


The easiest way to install pgcli is using Homebrew.


$ brew install pgcli


Alternatively, you can install pgcli as a python package using a package
manager called called pip. You will need postgres installed on your system
for this to work.

In depth getting started guide for pip -


$ which pip

If it is installed then you can do:


$ pip install pgcli

If that fails due to permission issues, you might need to run the command with
sudo permissions.


$ sudo pip install pgcli

If pip is not installed check if easy_install is available on the system.


$ which easy_install

$ sudo easy_install pgcli


In depth getting started guide for pip -

Check if pip is already available in your system.


$ which pip

If it doesn't exist, use your linux package manager to install pip. This
might look something like:


$ sudo apt-get install python-pip   # Debian, Ubuntu, Mint etc


$ sudo yum install python-pip  # RHEL, Centos, Fedora etc

pgcli requires python-dev, libpq-dev and libevent-dev packages. You can
install these via your operating system package manager.


$ sudo apt-get install python-dev libpq-dev libevent-dev


$ sudo yum install python-devel postgresql-devel

Then you can install pgcli:


$ sudo pip install pgcli


Pgcli can be run from within Docker. This can be useful to try pgcli without
installing it, or any dependencies, system-wide.

To build the image:


$ docker build -t pgcli .

To create a container from the image:


$ docker run --rm -ti pgcli pgcli <ARGS>

To access postgresql databases listening on localhost, make sure to run the
docker in "host net mode". E.g. to access a database called "foo" on the
postgresql server running on localhost:5432 (the standard port):


$ docker run --rm -ti --net host pgcli pgcli -h localhost foo

To connect to a locally running instance over a unix socket, bind the socket to
the docker container:


$ docker run --rm -ti -v /var/run/postgres:/var/run/postgres pgcli pgcli foo


Pgcli can be run from within IPython <>_ console. When working on a query,
it may be useful to drop into a pgcli session without leaving the IPython console, iterate on a
query, then quit pgcli to find the query results in your IPython workspace.

Assuming you have IPython installed:


$ pip install ipython-sql

After that, run ipython and load the pgcli.magic extension:


$ ipython

In [1]: %load_ext pgcli.magic

Connect to a database and construct a query:


In [2]: %pgcli postgres://someone@localhost:5432/world
Connected: someone@world
someone@localhost:world> select * from city c where countrycode = 'USA' and population > 1000000;
| id   | name         | countrycode   | district     | population   |
| 3793 | New York     | USA           | New York     | 8008278      |
| 3794 | Los Angeles  | USA           | California   | 3694820      |
| 3795 | Chicago      | USA           | Illinois     | 2896016      |
| 3796 | Houston      | USA           | Texas        | 1953631      |
| 3797 | Philadelphia | USA           | Pennsylvania | 1517550      |
| 3798 | Phoenix      | USA           | Arizona      | 1321045      |
| 3799 | San Diego    | USA           | California   | 1223400      |
| 3800 | Dallas       | USA           | Texas        | 1188580      |
| 3801 | San Antonio  | USA           | Texas        | 1144646      |
Time: 0.003s

Exit out of pgcli session with Ctrl + D and find the query results:


9 rows affected.
[(3793, u'New York', u'USA', u'New York', 8008278),
 (3794, u'Los Angeles', u'USA', u'California', 3694820),
 (3795, u'Chicago', u'USA', u'Illinois', 2896016),

 (3801, u'San Antonio', u'USA', u'Texas', 1144646)]

The results are available in special local variable _, and can be assigned to a variable of your


In [3]: my_result = _


A special thanks to Jonathan Slenders <>for
creating Python Prompt Toolkit <>
which is quite literally the backbone library, that made this app possible.
Jonathan has also provided valuable feedback and support during the development
of this app.

Click <>_ is used for command line option parsing
and printing error messages.

Thanks to psycopg <>_ for providing a rock solid
interface to Postgres database.

Thanks to all the beta testers and contributors for your time and patience. :)
