Remove code that refers to PostgreSQL 7.2 or older
We haven't had support for anything older than 7.3 for a long time, so this removes the code to save having to maintain it any further. Task-number: QTBUG-644 Change-Id: If0635f3bef5138a00a0e77011a70f23d0bffda32 Reviewed-by: Robert Szefner <robertsz27@interia.pl> Reviewed-by: Edward Welbourne <edward.welbourne@qt.io>
