Should be RETURNS BOOLEAN.

You might want to fix whatever client code you are using so that it
shows the error cursor, which would certainly have helped direct
your attention to the right place instead of the wrong one.  What
I see in psql is

ERROR:  syntax error at or near "RETURN"
LINE 2:                     oldValue IN VARCHAR ) RETURN BOOLEAN
                                                  ^
