Function Returning Table/Record

Hi,

I have a function that returns a subset of data from a specific table.
The function must return all the rows that are present in the parent
table.

Is there an easy way to create this function so that when the table
definition changes I don't need to change the function definition.

I know I can create the table to return RECORD but then when I call
the function I must specify the structure of the returned type.
Eg. SELECT * FROM my_func(args) AS foo(col type, ...);

There are a lot of columns so this is not a very practical solution.

Isn't there a shorter/better/easier way to do this?
