comment Reprojection problem with gdalwarp
-s_srs represents the projstring/epsg code of your source data, i.e. atnight.tif. -t_srs should be the proj string for your target/destination file, i.e. atnighttilt.tif. In most cases it's best to define both with gdalwarp

comment Reprojection problem with gdalwarp
you should define your -s_srs and check that the proj string for the tilted perspective is correct - are you sure +wktext needs to be appended to it?

comment Installing knn on PostgreSQL for windows
It's not clear from your post if you are installing the extension on a Windows machine or a Linux/Unix based system? 'make' and 'make install' are GNU Linux tools that create executables from a Makefile. The Makefile is included in the downloaded file you cited above.

comment Is there a zonal statistics tool to calculate median and mode raster values for each polygon?
the documentation page provided above states that the -e flag can be used to calculate the median value (as well as the percentiles). the mode shouldn't be too hard to calculate with some scripting.
