There is also a case insensitive regular expression operator (~*) but I don't
know if its faster than the two upper() function calls and it is
PostgreSQL-specific:
$sql = "select surname, firstname, title, company, worktel, ext, hometel,
mobile, email, emailtwo from employees where firstname ~* '{$criteria}'
or surname ~* '{$criteria}'";
See Bruce Momjian's book:
