QSqlRelationalDelegate::setEditorData() does not compile when
QT_NO_CAST_FROM_BYTEARRAY is defined. Since it's a public header this
will break user code.
Fix it by calling QByteArray::data() instead of relying on the
implicit cast.

The code snippets retrieving the native database driver handles was
using qstrcmp() wrong since that is returning 0 when the strings are
equal. In some snippets there was even a plain char * comparison which
would not work at all.
Fix all the places by correctly using qstrcmp() and replace the checks
for the valid pointer by not checking for 0.

When QSqlQueryModel or QSqlTableModel is created it will create a
QSqlQuery which defaults to using the default QSqlDatabase connection.
If this connection belongs to another thread then it will throw a
warning as this is not safe to use. Since the QSqlQuery is always
recreated when a query is set, the instance which is a member of
the class can effectively be invalid until a new one is set.

When a QComboBox is used as the editor for a relation inside a view then
it could end up showing the contents of the EditRole. This would be the
field which is used to represent the entry as opposed to the DisplayRole
which is what the user would expect to see is.
Therefore, setEditorData() is overridden to ensure that it is showing
the right data to the user. When the model gets updated, it will take the
corresponding EditRole value as before to ensure it is updated correctly.

We do add, remove or update third party code in minor releases,
sometimes even in patch level releases. However, the documentation is
supposed to be valid for all existing Qt 5 versions, but doing this for

Therefore rather make it explicit which Qt version the attributions
apply to. Also mention since when Qt is available under LGPLv3

[ChangeLog][QtSql][QPSQL] Added support for forward-only queries (requires
libpq version 9.2 or later)
[Important Behavior Changes] The QPSQL driver now supports forward-only
queries. To use this feature, you must build QPSQL plugin with PostreSQL
client library version 9.2 or later. See the Qt SQL documentation for
more information about QPSQL limitations of forward-only queries
(sql-driver.html).
[Important Behavior Changes] If you build the QPSQL plugin with PostgreSQL
version 9.2 or later, then you must distribute your application with
