Description

On QGIS Master 3.1, after I run a simple query such as `select * from my_table`, the result panel stays empty.

The query works well in QGIS 3.0 and in PgAdmin. But in 3.1, I can guess that the query is running because the panel is disabled while the query is running in the background. But then, the window is reactivated again but the result is not displayed.

It might be related to the display with MacOS?

I don't think it is related to MacOS, since I'm seeing the same problem with QGIS 3.1.0-Master (5b8599e9bb) on Windows.

It works when I run a query via Virtual Layers, but not with PostGIS directly, in which case I see a "Task Complete" notification, but no results.

The following Python error is logged:
