So you have a layer in QGIS that you want to export to PostgreSQL/PostGIS as a new database?

Create a new Database in Postgres

  • In your preferred database GUI (I use Dbeaver Community Edition), create the database.
  • Add the PostGIS extension! Execute the following:


Create the Postgres Connection in QGIS

Here are the steps:

  • In QGIS, locate the Browser panel
  • Right-click on PostGIS and select New Connection…
  • Complete the values for
    • Name e.g. fnweb31_omaps
    • Host e.g.
    • Database as created above e.g. omaps
    • (Optionally, turn on Allow saving/loading QGIS projects in the database)
  • Click Test Connection to verify it works
  • Enter credentials for Postgres
  • A message appears at the top of the dialog detailing whether the connection worked or not.
  • Click OK

There is a new connection on the expanded PostGIS branch of the Browser panel. Let’s keep going.

Open the DB Manager

  • Go to menu Database > DB Manager
  • Expand the PostGIS branch
  • Select the newly created fnweb31_omaps connection
  • Click the Import Layer/File… button in the ribbon
  • Change the Input dropdown to the layer you wish to import. The list of currently opened layers is pre-filled, or you can browse to another file.
  • Set the Schema to public unless you have other reasons for changing it
  • Set the table name to the desired name – it is prefilled with the existing name in QGIS or you can change it
  • Click OK
  • Re-enter credentials if required
  • Close the DB Manager dialog

Now we have a geographic layer stored in Postgres that can be queried, edited from anywhere and by any number of people. It’s fast, robust, and how things should be.
