Hack better NULL support on to (squee)
PQgetvalue used by squee returns null values as empty strings, which are
ambiguous for string fields. Therefore, use PQgetisnull to implement a
serialiser for squee which checks empty strings to see if they're actually a
NULL value, then returns '() in this case.
exec-query-with-null-handling can be used to access this behaviour.
