Fixes to question code.

• define items as a method items=get_items, not what is returned items=get_items() See Documentation

• The items method requires two arguments self and context

• Ensure the items method is defined before assigning argment to it Not doing so will result in

  NameError: name 'get_items' is not defined

Code

    # test call
    bpy.ops.importgis.database_connection('INVOKE_DEFAULT')

Made a minimal working example, run in test editor, pops up dialog with enum items from the update method.
