We stand with Ukraine
---------------------Ukrainian people are fighting for their country. A lot of civilians, women and children, are suffering. Hundreds were killed and injured, and thousands were displaced.
This is an image from my home town, Kharkiv. This place is right in the old city center.

.. image:: screenshots/image01.pngQuick Start
-----------If you already know how to install python packages, then you can simply do:
::
$ pip install -U pgcli
or
$ sudo apt-get install pgcli # Only on Debian based Linux (e.g. Ubuntu, Mint, etc)
$ brew install pgcli # Only on macOSIf you don't know how to install python packages, please check the
`detailed instructions`_... _`detailed instructions`: https://github.com/dbcli/pgcli#detailed-installation-instructions
Usage
-----::
$ pgcli [database_name]
or
$ pgcli postgresql://[user[:password]@][netloc][:port][/dbname][?extra=value[&other=other-value]]
Examples:
::
$ pgcli local_database
$ pgcli postgres://amjith:[email protected]:5432/app_db?sslmode=verify-ca&sslrootcert=/myrootcert
For more details:
::
$ pgcli --help
Usage: pgcli [OPTIONS] [DBNAME] [USERNAME]
Options:
-h, --host TEXT Host address of the postgres database.
-p, --port INTEGER Port number at which the postgres instance is
listening.
-U, --username TEXT Username to connect to the postgres database.
-u, --user TEXT Username to connect to the postgres database.
-W, --password Force password prompt.
-w, --no-password Never prompt for password.
--single-connection Do not use a separate connection for completions.
-v, --version Version of pgcli.
-d, --dbname TEXT database name to connect to.
--pgclirc FILE Location of pgclirc file.
-D, --dsn TEXT Use DSN configured into the [alias_dsn] section
of pgclirc file.
--list-dsn list of DSN configured into the [alias_dsn]
section of pgclirc file.
--row-limit INTEGER Set threshold for row limit prompt. Use 0 to
disable prompt.
--less-chatty Skip intro on startup and goodbye on exit.
--prompt TEXT Prompt format (Default: "\u@\h:\d> ").
--prompt-dsn TEXT Prompt format for connections using DSN aliases
(Default: "\u@\h:\d> ").
-l, --list list available databases, then exit.
--auto-vertical-output Automatically switch to vertical output mode if
the result is wider than the terminal width.
--warn [all|moderate|off] Warn before running a destructive query.
--help Show this message and exit.``pgcli`` also supports many of the same `environment variables`_ as ``psql`` for login options (e.g. ``PGHOST``, ``PGPORT``, ``PGUSER``, ``PGPASSWORD``, ``PGDATABASE``).
The SSL-related environment variables are also supported, so if you need to connect a postgres database via ssl connection, you can set set environment like this:
::
export PGSSLMODE="verify-full"
export PGSSLCERT="/your-path-to-certs/client.crt"
export PGSSLKEY="/your-path-to-keys/client.key"
export PGSSLROOTCERT="/your-path-to-ca/ca.crt"
pgcli -h localhost -p 5432 -U username postgres.. _environment variables: https://www.postgresql.org/docs/current/libpq-envars.html
Features
--------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
completion.- ``SELECT * FROM `` will only show table names.
- ``SELECT * FROM users WHERE `` will only show column names.* Primitive support for ``psql`` back-slash commands.
* Pretty prints tabular data... _prompt_toolkit: https://github.com/jonathanslenders/python-prompt-toolkit
.. _tabulate: https://pypi.python.org/pypi/tabulateConfig
------
A config file is automatically created at ``~/.config/pgcli/config`` at first launch.
See the file itself for a description of all available options.Contributions:
--------------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.https://github.com/dbcli/pgcli/blob/master/DEVELOP.rst

-----------------------------------macOS:
======The easiest way to install pgcli is using Homebrew.
::
$ brew install pgcli
Done!
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`` - https://pip.pypa.io/en/latest/installation/
::
$ 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
Linux:
======In depth getting started guide for ``pip`` - https://pip.pypa.io/en/latest/installation/
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
or
$ 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
or
$ sudo yum install python-devel postgresql-devel
Then you can install pgcli:
::
$ sudo pip install pgcli
Docker
======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
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
IPython
=======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;

Pgcli dropped support for Python<3.8 as of 4.0.0. If you need it, install ``pgcli <= 4.0.0``.
Thanks:
-------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. :)
