Thank you to everybody for your help! Now, the map file is fixed.
I changed the projection to EPSG:4326 and the associated coordinates of the extent (e.g. 13.7 50.6 15.3 51.8). In the DATA string I left out the schema attribut. The png of the tool shp2img is showing the points.
Greetings, Geograefin

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
