Today, PostgreSQL is commonly abbreviated as Postgres. In 1996, the POSTGRES project was renamed to PostgreSQL to clearly illustrate its support for SQL. The goal of the POSTGRES project was to add the minimal features needed to support multiple data types. The project was originally named POSTGRES, in reference to the older Ingres database which also developed at Berkeley. ![]() The PostgreSQL project started in 1986 at Berkeley Computer Science Department, University of California. PostgreSQL’s community pronounces PostgreSQL as /ˈpoʊstɡrɛs ˌkjuː ˈɛl/. PostgreSQL is used as a primary database for many web applications as well as mobile and analytics applications. PostgreSQL is a highly stable database backed by more than 20 years of development by the open-source community. PostgreSQL supports both SQL (relational) and JSON (non-relational) querying. PostgreSQL is an advanced, enterprise-class, and open-source relational database system. Once a database is created using either of the above-mentioned methods, you can check it in the list of databases using \l, i.e.Let’s start with a simple question: what is PostgreSQL? Hence, provide a password and proceed to create your new database The above given command will prompt you for password of the PostgreSQL admin user, which is postgres, by default. Go to the bin directory and execute the following command to create a database.Ĭreatedb -h localhost -p 5432 -U postgres testdb Open the command prompt and go to the directory where PostgreSQL is installed. Specifies the TCP port or the local Unix domain socket file extension on which the server is listening for connections.įorce createdb to prompt for a password before connecting to a database. Specifies the host name of the machine on which the server is running. Show help about createdb command line arguments, and exit. Specifies the template database from which to build this database. Specifies the locale to be used in this database. Specifies the character encoding scheme to be used in this database. Specifies the default tablespace for the database.Įcho the commands that createdb generates and sends to the server. The following table lists the command line arguments createdb accepts − S. Specifies a comment to be associated with the newly created database.Ĭommand-line arguments, which createdb accepts. The table given below lists the parameters with their descriptions. The syntax for createdb is as shown below −Ĭreatedb ] The only difference between this command and SQL command CREATE DATABASE is that the former can be directly run from the command line and it allows a comment to be added into the database, all in one command. PostgreSQL command line executable createdb is a wrapper around the SQL command CREATE DATABASE. The following is a simple example, which will create testdb in your PostgreSQL schema Where dbname is the name of a database to create. ![]() The basic syntax of CREATE DATABASE statement is as follows − By default, the new database will be created by cloning the standard system database template1. This command will create a database from PostgreSQL shell prompt, but you should have appropriate privilege to create a database. Using createdb a command-line executable. ![]() PostgreSQL provides two ways of creating a new database − This chapter discusses about how to create a new database in your PostgreSQL.
