[QGIS-Developer] Loading pg raster crashes QGIS

[Paolo Cavallini]

Hi all,
I think the crash when zooming after loading a pg raster is back, both
in 3.4 and in master:
* load a single band raster from either Browser or DB Manager
* zoom in and out
* crash.
I'm struggling to find a way of consistently replicating this, using
tiles vs untiled rasters of different sizes, but it happens very often.
Occasionally it hangs QGIS, with the progress bar moving and no effect.
Any hint on what I can check?
Two different error messages in different occasions, see below.
Cheers.
