pgcli 4.1.0

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.

A REPL for Postgres

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

Home Page: http://pgcli.com

MySQL Equivalent: http://mycli.net

Quick 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 macOS

If you don’t know how to install python packages, please check the detailed 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:pa$$w0rd@example.com: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

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 <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.

Config

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.

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. :)
