In this example, we'll show you how to briefly set up pgAdmin, upload some data, and use the geometry viewer to view your geospatial queries in pgAdmin. The geometry viewer was built thanks to a Google Summer of Code project by Xuri Gong, which allows you to view geometry and geography data in the pgAdmin browser on an OpenStreetMap map.
With the latest release, version 3.3, we got something really helpful for GIS developers: the geometry viewer. Since pgAdmin 4 was released last year, it's had some significant updates and bug fixes. In our last article on pgAdmin 4 version 1.6, we covered its installation and how to use it with Compose for PostgreSQL databases. In this GeoFile, we'll show you how to set up pgAdmin 4, import some data, add PostGIS, and start using the geometry viewer.
With the release of pgAdmin 4 version 3.3 comes the geometry viewer that will display your geometry (or geography) data on OpenStreetMap.

If you call a procedure that returns multiple result sets in PSQL tool, pgAdmin Query tool or another function, the query returns cursor names:
