Ticket #837 (closed defect: fixed)
[raster] ST_MapAlgebra -- I think we have a memory leak
|Reported by:||robe||Owned by:||jorgearevalo|
Description (last modified by robe) (diff)
I tried to do this on my test elephant
-- its a single tile -- I forget the size OALTER TABLE ch13.pele ADD column map_rast raster; UPDATE ch13.pele SET map_rast = ST_MapAlgebra(rast,'CASE WHEN rast BETWEEN 100 and 250 THEN 1 WHEN rast = 252 THEN 2 WHEN rast BETWEEN 253 and 254 THEN 3 ELSE 0 END', '2BUI') ;
and it crashes the server after about 13 seconds.
This is on Windows XP latest trunk.
