Spgist support functions are those you register yourself in the OPERATOR
CLASS creation. What does it mean they don't support geometry datatypes ?
And why is it a box2df if we already found out some weeks ago that spgist
does not support an index storage type different from the target type ?

If you pass "%d" as the format string, the generated code will print
an integer whatever you pass as an argument. You want to use "%p" to
print a memory address. See `man 3 printf`.
