PostGIS Raster driver: overviews found as non regular

Description
It seems that the driver is not recognizing the overviews created by the default loader as regular overviews. I've performed a few tests using the python console: In [5]: band=f.GetRasterBand(1) In [6]: band.GetOverviewCount() Out[6]: 0 In [8]: band.HasArbitraryOverviews() Out[8]: True
On this table I created the 2,4,8,16 overviews altogether. I've checked the raster_overviews view in postgresql and there are 4 lines, correctly described as the overviews. I've also been able to read the overview tables in the QGIS plugin by choosing them instead of the base raster. I made my tests using ubuntu 11.10, gdal 1.9, postgis 2.0, qgis 1.7.
Since this is disables the overview reading, the driver's performance is greatly decreased.

This ticket has been automatically closed because Trac is no longer used for GDAL bug tracking, since the project has migrated to GitHub. If you believe this ticket is still valid, you may file it to https://github.com/OSGeo/gdal/issues if it is not already reported there.
I think the problem is solved after r24867. If you can confirm it's working, I close the ticket.
