The PL/pgSQL documentation for 8.0 and earlier says this:

The return value of a function cannot be left undefined. If control
reaches the end of the top-level block of the function without hitting
a RETURN statement, a run-time error will occur.

The 8.1 Release Notes show that this requirement has been removed:

* No longer require functions to issue a RETURN statement (Tom)

This is a byproduct of the newly added OUT and INOUT functionality.
RETURN can be omitted when it is not needed to provide the function's
return value.
