Running ST_Reskew with a large enough raster seems to result in a performance cliff or infinite loop.
SELECT ST_Rotation(ST_Reskew(ST_AddBand(ST_MakeEmptyRaster(100, 430, 0, 0, 0.001, -0.001, 0, 0, 4269), '8BUI'::text, 1, 0), 0.0015));
Note:
See TracTickets
for help on using tickets.
The issue seems to be an infinite loop.
