Loss of some parts of the function definition

Hi,

Dear developers, I have a request to you.

Now create a script in the application of its function parameters and
return values can be declared using %TYPE.
However, when you save the script is stored inside the server only what is
considered his body. Thus, we obtain:
1) loss of the custom formatting.
2) loss of communication parameters and return types with these types of
fields to create the function.
3) multidimensional arrays are transformed into one-dimensional: [][] -> []
4) loss of data accuracy: numeric(n,m) -> numeric

Please - how to save and restore the entire text of the definition to
CREATE END; unchanged.
