First of all, we should upload our random houses in our spatial database. In order to do this, let's open QGIS's database manager through Database | DB Manager | DB Manager. Connect to the PostGIS database with the role we have--write privileges--and import the houses layer with Import layer/file. Of course, we have to open our raw houses layer, as it is not opened in QGIS. The options should be the same as before, which are as follows:
- Use the spatial schema.

When we are done, let's visualize the uploaded houses layer in QGIS, and remove the one saved to the...
