Description
In a plugin I add a feature to a PostGIS layer. I have another WMS raster layer connected to this PostGIS layer.
If I invoke the command:
[[QgsMapCanvas]].refresh()
it refreshes the map but not the WMS layer. A workaround is this (note: 'e' variable is QMouseEvent type):
self.myCanvas.panAction(e)
self.myCanvas.panActionEnd(QPoint (e.x(), e.y()))

Try to reload the layers before refreshing the canvas (that's how qgisapp does it):
C++:
QgsMapLayerRegistry::instance()->reloadAllLayers();
mMapCanvas->refresh();
Python:
QgsMapLayerRegistry.instance().reloadAllLayers()
qgis.utils.iface.mapCanvas().refresh()
Hope it works (otherwise reopen the ticket)
