![]() However, if it errors out, you can locate the psql utility by searching for the file with the following command on /]# find / -name psql This gives you the path, and also, since the OS knows the location, you will not need to browse for it. You can try the following command on the data]# which psql The easiest way to connect is to check whether you already have psql in your environment variables on not. To connect using psql you will first need to locate its location on the operating system that you might be using: i. PostgreSQL is supported on three major platforms. ![]() Since this is probably the first time you are trying to connect to a PostgreSQL database that you have installed, we will cover some of the possible scenarios you may encounter so you can start working in just a short period of time. So let’s take our first steps and get connected to PostgreSQL. Here I offer separate steps for users of different operating systems, where required in cases where the operating system is not specified, the steps can be treated as a universal approach, and are valid for any operating system that you are using. Since terminal/command line and pgAdmin are the most favored ways for connecting to PostgreSQL, I explain the basics of using both methodologies. For this, we will go to the home button and search for pSQL and open it.This is a two-part article for beginners who have installed the most advanced open source database, PostgreSQL, and are now looking to connect to it. Firstly, we will open the SQL shell in our local system.To create a database in the command line, we are going to follow the below steps: Create Database command is not found: If PostgreSQL is not installing correctly, we may encounterthis type of error, and we need to execute the Create Database command from our PostgreSQL installation path.And the PostgreSQL account is created but does not have access to create a database. Permission is not granted to create a database: This error will occur when we need to give authorization to the related users for using the create command.No such file in the server is executing locally and accepting connections on the Unix domain socket: If we use the create database command and the server is not started then we get the error.We can encounter the below errors while we are using the create database command: ![]() This parameter is used to define the maximum parallel connections of a new database, and by default, it is -1 (unlimited). It is used to define the tablespace name for the new database, and by default, it is the template database's tablespace. This parameter is used to display the character classification for the new database. It is used to define the sort order of strings that mark the result of the ORDER BY clause if we are using a SELECT statement. It is used to describe the character set encoding for the new database, and by default, it is UTF8. While creating the new database, we will require database template name. It is used to describe the role name for the user who will have the new database, and by default, it is postgres. And we also ensure that the database must be unique because If we try to create a new database with the same name as an existing database, it will show an error. We will use this parameter to specify the new database name, which we want to create. In the above syntax, we have the following parameters: Parameters The complete Syntax for creating a Database in PostgreSQL is as following:ĬONNECTION LIMIT = max_concurrent_connection
