- Set up SQL Workbench/J for PostgreSQL on Linux, Windows, and macOS.This simple guide deliveres clear-cut instructions and a ton of relevant images.
- First, launch the psql program and connect to the PostgreSQL Database Server using the postgres user: Second, enter all the information such as Server, Database, Port, Username, and Password. If you press Enter, the program will use the default value specified in the square bracket and move the cursor to the new line.
PostgreSQL ODBC for Windows. This tutorial shows how to set up a data source and connect to a PostgreSQL database using the Database Explorer app or the command line. This tutorial uses the PostgreSQL ANSI(x64) driver to connect to a PostgreSQL 9.2 database. Verify the driver installation. Download PgAdminPortable for free. PostgreSQL Tools. PgAdmin Portable is the PgAdmin whatever it is packaged with a PortableApps.com launcher as a portable app, so you can manage PostgreSQL 7.3 and above running on any platform, as well as commercial and derived versions of PostgreSQL such as Postgres Plus Advanced Server and Greenplum database on your iPod, USB flash drive, portable hard.
These instructions are for PostgreSQL 9.1 and higher, PostGIS 2.2 and higher that is compiled with raster support.Note: if you have postgis, without raster support, you can not use CREATE EXTENSION. Refer to PostGIS install.
Enabling PostGIS
PostGIS is an optional extension that must be enabled in each database you want to use it in before you can use it. Installing the software is just the first step.DO NOT INSTALL it in the database called
postgres
.Connect to your database with
psql
or PgAdmin. Run the following SQL.You need only install the features you want:Upgrading PostGIS
To upgrade PostGIS, you first have to install the latest binaries and then upgrade each database you have PostGIS installed in
For example connect to database you want to upgrade and if you just installed binaries for 2.1.3You can upgrade from 2.0 to 2.1, 2.2 et.c using this approach. To go from 1.* to 2.* you need to do a hard upgrade.Refer to PostGIS install for more extensive instructions.Note: that as of PostGIS 2.1.3 and PostGIS 2.0.6, you need to set environment variables to get full features.

Summary: in this tutorial, you will learn how to connect to the PostgreSQL Database Server via an interactive terminal program called psql and via the pgAdmin application.
When you installed the PostgreSQL database server, the PostgreSQL installer also installed some useful tools for working with the PostgreSQL database server. In this tutorial, you will learn how to connect to the PostgreSQL database server via the following tools:
- psql – a terminal-based front-end to PostgreSQL database server.
- pgAdmin – a web-based front-end to PostgreSQL database server.
1) Connect to PostgreSQL database server using psql
psql is an interactive terminal program provided by PostgreSQL. It allows you to interact with the PostgreSQL database server such as executing SQL statements and managing database objects.
The following steps show you how to connect to the PostgreSQL database server via the psql program:
First, launch the psql program and connect to the PostgreSQL Database Server using the postgres user:
Second, enter all the information such as Server, Database, Port, Username, and Password. If you press Enter, the program will use the default value specified in the square bracket
[]
and move the cursor to the new line. For example, localhost
is the default database server. In the step for entering the password for user postgres, you need to enter the password the user postgres that you chose during the PostgreSQL installation.Third, interact with the PostgreSQL Database Server by issuing an SQL statement. The following statement returns the current version of PostgreSQL:
Please do not forget to end the statement with a semicolon (;). After pressing Enter, psql will return the current PostgreSQL version on your system.
2) Connect to PostgreSQL database server using pgAdmin
The second way to connect to a database is by using a pgAdmin application. The pgAdmin application allows you to interact with the PostgreSQL database server via an intuitive user interface.
The following illustrates how to connect to a database using pgAdmin GUI application:
First, launch the pgAdmin application.
The pgAdmin application will launch on the web browser as shown in the following picture:
Second, right-click the Servers node and select Create > Server… menu to create a server
Third, enter the server name e.g., PostgreSQL and click the Connection tab: Eon 2 6 4 – simple and elegant time tracking.
Renamer 5 2 6 – rename files in batches. Fourth, enter the host and password for the postgres user and click the Save button:

Fifth, click on the Servers node to expand the server. By default, PostgreSQL has a database named postgres as shown below:
Sixth, open the query tool by choosing the menu item Tool > Query Tool or click the lightning icon.
Seventh, enter the query in the Query Editor, click the Execute button, you will see the result of the query displaying in the Data Output tab:
Connect to PostgreSQL database from other applications
Any application that supports ODBC or JDBC can connect to the PostgreSQL database server. In addition, if you develop an application that uses a specific driver, the application can connect to the PostgreSQL database server as well:
