![]() This will prompt you with a Create-Database window. To create a new database, right click on Databases in the tree control > click on Create > and then select Database. For first time users, a default database will be created called postgres as shown in the image below. The password to be entered will depend on whether a password was set up during installation.Īfter entering the password, you will see the server connected in the Browser section on the left hand side of the interface (the left side is known as the tree control). To connect to the server, right click on PostgreSQL 10, then select Connect Server. ![]() In our case, we will be connecting to localhost as a server. Once you have PostgreSQL 10 and pgAdmin 4 installed (there are many online resource on how to do that), you will need to connect to a PostgreSQL server on pgAdmin. In this tutorial we’ll be working with PostgreSQL using a GUI called pgAdmin, which is an open source software that is used to connect to and manage PostgreSQL databases. PostgreSQL can be used either through a GUI or using the command line. As a database server its main functionality is to store data securely and return and retrieve data upon request from other software applications. PostgreSQL is an open source object-relational database management system (ORDBMS) that runs on all major operating systems, including but not limited to, Linux, macOS and Windows. Prerequisite tasks: Install PostgreSQL 10 and pgAdmin 4 on your computer. Create queries using the Scripts option.Brief overview of PostgreSQL and pgAdmin. ![]() ![]() It will be one of many tutorials that I will write to cover some of the lab material that I will be teaching this semester. This blog is written in the form of a tutorial on how to use PostgreSQL using the pgAdmin 4 graphical user interface. The documentation for the current version of Postgresql 9.6 can be found here Previous versions are also available near that link but in the case of pg_hba.conf things do not appear to have changed between versions.PostgreSQL Beginner Tutorial I: Getting Started with pgAdmin 4 This basically says "Anybody from anywhere can access my Postgresql server" I have provided it simply as an example of how careful you have to be. If you were particularly reckless and irrisponsible and enjoy the prospect of living dangerously and with regular intervals of fear and loathing you would use the following line in your pg_hba.conf file, although I seriously council against it. The above example will get you going but it would be wise to go and briefly read the postgresql documentation for the pg_hba.conf file. If you wish to allow all computers in your subnet to access your Postgresql server you may do something like the following: # IPv4 local connections: This says that only allow the hosts that match 127.0.0.1/32 to access my server. The following snippet is from my own Postgresql server: # IPv4 local connections: By default it only allows a user local to the server to connect to the database. To allow users in the wide world to access your server is unwise. To allow yourself access to the server to administer it on the same subnet is very easy. ![]() Are you wanting to administer Postgresql from the local network or are you wanting to allow other users in the wide world to connect to your Postgresql server? ![]()
