+"ST_Collect and ST_Union are often interchangeable. ST_Collect is in general "
+"orders of magnitude faster than ST_Union because it does not try to dissolve"
+" boundaries or validate that a constructed MultiPolgon doesn't have "
+"overlapping regions. It merely rolls up single geometries into MULTI and "
+"MULTI or mixed geometry types into Geometry Collections. Unfortunately "
+"geometry collections are not well-supported by GIS tools. To prevent "
+"ST_Collect from returning a Geometry Collection when collecting MULTI "

Si se le da una carpeta de imágenes al comando raster2pgsql, se calcularán previsualizaciones de cada archivo de imagen y se cargarán por separado. El Nivel 1 supone siempre el archivo original. Nivel 2 tendrá cada tesela representada por 4 de la original. Por ejemplo, si tienes una carpeta de archivos de imagen de 5000x5000 pixeles que decidiste dividir en imágenes de 125x125 , para presentar cada imagen tu tabla base tendrá (5000*5000)/(125*125)=1.600 registros , tu tabla (l=2) <varname>o_2</varname> tendrá un tope de (1600/Potencia (2,2))=400 filas , tu (l=3) <varname>o_3</varname> tendrá un tope de (1600/Potencia (2,3)) = 200 filas. Si los píxeles no son divisibles por el tamaño de tus teselas , obtendrás algunas de relleno (teselas no completamente llenas ) . Ten en cuenta que cada tesela de previsualización generada por el comando raster2pgsql tiene el mismo número de pixeles que la tesela de origen , pero es de menor resolución que cada pixel de la que representa (Potencia(2,factor_de_previsualizacion) pixeles del original) ."
