Some interesting flags (to see all, use -h or --help depending on your psql version):

  • -E: will describe the underlaying queries of the commands (cool for learning!)
  • -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Most d commands support additional param of __schema__.name__ and accept wildcards like *.*

Postgres Version Command
  • q: Quit/Exit
  • c __database__: Connect to a database
  • d __table__: Show table definition including triggers
  • d+ __table__: More detailed table definition including description and physical disk size
  • l: List databases
  • dy: List events
  • df: List functions
  • di: List indexes
  • dn: List schemas
  • dt *.*: List tables from all schemas (if *.* is omitted will only show SEARCH_PATH ones)
  • dT+: List all data types
  • dv: List views
  • df+ __function__ : Show function SQL code.
  • x: Pretty-format query results instead of the not-so-useful ASCII tables
  • copy (SELECT * FROM __table_name__) TO 'file_path_and_name.csv' WITH CSV: Export a table as CSV

Mini Bytes: In this tutorial i am going to explain you about how to install PostgreSQL 10 in windows 10 and Linux operating system. Since there are many ways to install PostgreSQL 10, i am going to follow GUI installation in Window 10 and command line installation in Linux (Ubuntu 17.04 & CentOS 7). The pgconfig command will report the directory where the PostgreSQL programs are installed (-bindir), the location of C include files (-includedir) and object code libraries (-libdir), and the version of PostgreSQL (-version): $ pgconfig -version PostgreSQL 9.3.6. Is there a way to check which version of Postgres is installed on a particular Linux box without query the RPM database? For instance, is there a 'psql -version' command, or something similarthat I can use? ThanksJohn - Sent via pgsql-admin mailing list (pgsql-admin(at)postgresql(dot)org) To make changes to your.

  • du: List users
  • du __username__: List a username if present.
  • create role __test1__: Create a role with an existing username.
  • create role __test2__ noinherit login password __passsword__;: Create a role with username and password.
  • set role __test__;: Change role for current session to __test__.
  • grant __test2__ to __test1__;: Allow __test1__ to set its role as __test2__.

Configuration

  • Service management commands:
  • Changing verbosity & querying Postgres log:
    1) First edit the config file, set a decent verbosity, save and restart postgres:
  1. Now you will get tons of details of every statement, error, and even background tasks like VACUUMs

Create command

There are many CREATE choices, like CREATE DATABASE __database_name__, CREATE TABLE __table_name__ .. Parameters differ but can be checked at the official documentation.
