QDateTime does not parse a PostgreSQL timestamp with timezone as a Qt::ISODate

QDateTime is unable to parse a datetime from a PostgreSQL column of PostgreSQL data type "timestamp with timezone" which returns a valid ISO 8601 datetime (of the form yyyy-MM-dd HH:mm:ss(+/-)offset from GMT) anymore. This use to work in 5.1.1 and older but no longer works in 5.2.0 . Looking in qdatetime.cpp (as part of a preliminary investigation), It seems that the implementation has changed from 5.1.1 to 5.2.0.
