Fred, your original example made it look like you were writing "
(one double quote mark) where what you need to write is ''
(two single quote marks).  The reason is that you are trying to
embed a single quote mark in the value of a string literal.
(If you are using PG 8.0 I'd suggest adopting the dollar-quoting
style for entering the function body, instead.)

Another problem I noticed is you were leaving off required
statement-ending semicolons, which could also prevent the plpgsql
parser from recognizing the RAISE command properly.

You might try something simpler just to get your feet wet:

    create function hello_world(text) returns text as '
    begin
        raise notice ''I got %'', $1;
        return $1;
    end' language plpgsql;

    select hello_world('Hi there!');

Once you get past that you'll have some idea about the quote marks
anyway ...
