Gdaladdo behaves badly with multitable rasterlite DB

Description (last modified by Even Rouault)

Tested with GDAL 1.9.0, gdal_translate and gdaladdo. Gdaladdo seems to make something wrong with rasterlite databases which contain several raster tables.

The following example is using 3 tables, one of them having a different native resolution but the error happens also with only two tables and both having the same pixel size. Error is not only with gdalinfo, Quantum GIS also opens the second and third table as they had the bigger, faulty pixel size. 

Building rasterlite DB from 3 originals
=======================================
gdal_translate -of rasterlite -a_srs epsg:2393 18m.tif
rasterlite:multitest.sqlite,table=raster_1
Input file size is 4000, 4000

gdal_translate -of rasterlite -a_srs epsg:2393 18n.tif
rasterlite:multitest.sqlite,table=raster_2
Input file size is 4000, 4000

gdal_translate -of rasterlite -a_srs epsg:2393 18mb.tif
rasterlite:multitest.sqlite,table=raster_3
Input file size is 2000, 2000

Check gdalinfo; everything OK 
=============================
gdalinfo rasterlite:multitest.sqlite,table=raster_1
Driver: Rasterlite/Rasterlite
Files: multitest.sqlite
Size is 4000, 4000
Origin = (3180000.000000000000000,6640000.000000000000000)
Pixel Size = (20.000000000000000,-20.000000000000000)

gdalinfo rasterlite:multitest.sqlite,table=raster_2
Driver: Rasterlite/Rasterlite
Files: multitest.sqlite
Size is 4000, 4000
Origin = (3260000.000000000000000,6640000.000000000000000)
Pixel Size = (20.000000000000000,-20.000000000000000)

gdalinfo rasterlite:multitest.sqlite,table=raster_3
Driver: Rasterlite/Rasterlite
Files: multitest.sqlite
Size is 2000, 2000
Origin = (3180000.000000000000000,6640000.000000000000000)
Pixel Size = (40.000000000000000,-40.000000000000000)

Add overviews
