I have tested my function some more and found out that it is while i am trying 
to return it crashes. If i use a standard type like float it works, but with 
my own type alignres it doesn't. I have used this type as return value in 
other functions before, but not in set returning functions.

When returning a float value, SRF_RETURN_NEXT(funcctx, Float8GetDatum(result)) 
is used. What am i supposed to use for my own type to get the datum value? I 
have tried using PointerGetDatum(result) but then the function crashes.
