It could also be your extents:
- remove all layers from your mapfile, except for the PG one
- remove all projection blocks from your mapfile
- connect through ogrinfo commandline to that layer
ogrinfo PG:"host=127.0.0.1 user=postgres password=postgres
dbname=test port=5432"
- use the ogrinfo command with the layername and the -summary switch to
get the PG layer's extents
ogrinfo PG:"host=127.0.0.1 user=postgres password=postgres dbname=test
port=5432" yourPGlayername -summary
- use that extent for the EXTENT parameter in your mapfile
- re-test with shp2img command
shp2img -m postgis.map -o ttt.png -map_debug 3

If you get an image then at least no error is being generated. Are you
sure the layer you’re trying to view is on? There’s a switch in shp2img
to turn on a layer or you can set STATUS DEFAULT in the layer definition.

looks like this is a png-image. Have you tried to open this file with an
image-viewer?
