Not for 7.1, I'm afraid.  EXECUTE doesn't provide *any* connection
to the plpgsql function's local namespace; it just hands off the
constructed string to the main SQL parser.

In most cases you can work around this by interpolating the variable's
value into the constructed string, eg,
execute ''update foo set bar = '' || new.bar;

Use quote_literal() when interpolating a nonnumeric value this way.

I do have some ideas about improving the situation in 7.2 or later ...
