This error is known to me. But don't ask me what the intrinsic reason is. It occurs once and then never again. It has sth. to do with the new table column "osm_meta" introduced in Version 4.6.9.

Delete your wmCar_2po_4pgr table manually and try again.

Why won't osm2po setup table correctly?
This is something it will be useful for several things now that I started "photoshoping" - so I made some lines with the pen tool, then right clicked with the 'direct selection' and then 'stroke path' to paint the lines. 

Now, this lines are closed, they make a shape, if I paint the inside with the bucket tool it creates white spaces inbetween the border and the filling!

How does one fill properly in photoshop?
