In general you need to look at existing code that does something
similar to what you want to do and model your new code after it. It's
not really possible to speculate as to what you might have done wrong
or what you ought to do instead from the information you've provided
here.
If you are considering proposing your patch for inclusion in the
PostgreSQL upstream sources, you should first discuss why you are
trying to do this and what you hope to get out of it. There might be
a way to do whatever it is you are trying to do without modifying the
source code.
