Data Fields
GNUNET_PQ_ResultConverter	conv
	What is the format of the result?
GNUNET_PQ_ResultCleanup	cleaner
	Function to clean up result data, NULL if cleanup is not necessary.
void *	cls
	Closure for conv and cleaner.
void *	dst
	Destination for the data.
size_t	dst_size
	Allowed size for the data, 0 for variable-size (in this case, the type of dst is a void ** and we need to allocate a buffer of the right size).

	Field name of the desired result.
size_t *	result_size
	Where to store actual size of the result.
bool	is_nullable
	True if NULL is allowed for a value in the database.
bool *	is_null
	Points to a location where we should store "true" if the result found is NULL, and otherwise "false".
