[QGIS-Developer] "Refresh" is 'refresh data' for Postgis and only 'repaint' for OGR?

[Richard Duivenvoorde]

Hi Devs,

Anybody has knowledge about the difference between the menu item:
"Refresh (F5)"
And the 
"Refresh layer at interval (seconds)" in the Layer Properties dialog?

Because with me the F5 mostly works, 
while the autorefresh in the layer props works for postgres, but not for other (ogr?) layers.

I tried to find differences between those two providers, but I only seen links to rendering, not about reloading (provider) data.

Any hints appareciated.

Regards,
