In a non-grouped query like the above, I don't think that the order by is
meaningful. You only get one row back anyway without a group by, and
there's no single zipCode or houseNumber to associate with the row.
What do you mean by a non-grouped query? The query below gives the same
error:
SELECT zipcode, COUNT(*) FROM prototype.customers, prototype.addresses
WHERE
customers.contactaddress = addresses.objectid
AND
zipCode < '2716BN'
Try
SELECT COUNT(*)
FROM prototype.customers, prototype.addresses
WHERE customers.contactaddress = addresses.objectid
AND zipCode < '2716BN'

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
