The manual ogrinfo way is the only one using GDAL utilities.

We should probably extend the -sql "DELLAYER:xxxx" syntax to work with raster tables as 
well. Actually I see we currently also catch "DROP TABLE xxxx" to drop the table and remove 
links in other tables in the vector case (so with th same effect as DELLAYER:xxxxx). Would 
you mind creating an enhancement ticket about that ?

There's ongoing work on the QGIS side (dev version only I guess) to offer in the DBManager a 
way to delete raster layers (issuing the SQL requests under the hood)
