Connecting to the PostgreSQL database with pgAdmin

There are a number of front-end tools available for connecting to, and working with, the PostgreSQL database. Among the most popular are psql, a command-line tool for querying the database, and the free and open source graphical tool pgAdmin.

Any data querying and manipulation you can do with pgAdmin can also be done at the command line with psql.

Note

This section uses the graphical utility pgAdmin which may not be automatically present, depending on the type of installation of OpenGeo Suite. Please see the Installation section for information on how to install these tools for your platform.

Launching pgAdmin

Depending on how OpenGeo Suite was installed pgAdmin may or may not have been installed. See the Installation section for installation instructions. Once installed follow the instructions below for your platform.

Working with pgAdmin

Depending on how you installed OpenGeo Suite, you may already have one pre-configured PostGIS server, localhost:5432, listed in the pgAdmin Object browser.

PostGIS server in pgAdmin

If you don’t have an entry for PostGIS listed, add a new server connection manually. Click File ‣ Add Server and complete the New Server Registation dialog box to register a new server. Ensure the Host is set to localhost and Port is 5432 (unless you have configured PostgreSQL for a different port).

Querying a database

Note

If you are just installing OpenGeo Suite for the first time, there will only be a generic “postgres” database installed, with no tables, and you will need to create a new spatial database.
