[raster] speed up ST_Envelope
|Reported by:||strk||Owned by:||Bborie Park|
I noticed that ST_Envelope(rast) is implemented as ST_Envelope(ST_ConvexHull(rast)).
I'm not sure if that's necessary. Ideally ST_Envelope should be able to give a response by only looking at the raster header, without even fully detoasting the raster.
