Initial Comment:
I've found a case where psqlODBC doesn't match JODBC, psql, or Perl-DBD::Pg. It looks like a numeric/floating point issue perhaps?

Using psqlodbc-08.00.0100 and psqlodbc-08.01.0200. Both compiled as 64bit, Postgres 8.0.1.

Sample code:

CREATE OR REPLACE FUNCTION plpgsql_multiply(numeric, float) RETURNS numeric AS $$
DECLARE
BEGIN
RETURN $1 * $2;
END
$$ LANGUAGE plpgsql;

CREATE OR REPLACE FUNCTION perl_ge(numeric, float) RETURNS bool AS $$
if ($_[0] >= $_[1]) { return true; }
return false;
$$ LANGUAGE plperl;

SELECT perl_ge(47.3, plpgsql_multiply(43, 1.1));

-- true using JODBC, DBD::Pg, psql
-- false using ODBC
