In order to save having to always run a query to get the tablename for
a known oid then we cache the result on the driver side. The oid stays
the same while the table exists, so only on dropping it would it change.
Recreating the table causes it to get a new oid, so there is no risk of
the old one being associated with the wrong table when this happens, if
the driver is still open at that point.

Commit 12c5264d9a fixed the calculation of
SHA-3 in QCryptographicHash: we were previously calculating Keccak.
Unfortunately, turns out that replacing the algorithm wasn't the best
idea: there are people who need to compare with the result obtained from
a previous version of Qt and stored somewhere. This commit restores the
enum values 7 through 10 to mean Keccak and moves SHA-3 to 12 through
15. The "Sha3_nnn" enums will switch between the two according to the
QT_SHA3_KECCAK_COMPAT macro.
[ChangeLog][Important Behavior Changes] This version of Qt restores
compatibility with pre-5.9.0 calculation of QCryptographicHash
algorithms that were labelled "Sha3_nnn": that is, applications compiled
with old versions of Qt will continue using the Keccak algorithm.
Applications recompiled with this version will use SHA-3, unless
QT_SHA3_KECCAK_COMPAT is #define'd prior to #include
<QCryptographicHash>.
[ChangeLog][Binary Compatibility Note] This version of Qt changes the
values assigned to enumerations QCryptographicHash::Sha3_nnn.
Applications compiled with this version and using those enumerations
will not work with Qt 5.9.0 and 5.9.1, unless QT_SHA3_KECCAK_COMPAT is
defined.

... as it has outlived its original purpose:
Qt3 implementation on X11:
void QApplication::flush() { flushX(); }
void QApplication::flushX() { if (appDpy) XFlush( appDpy ); }
Qt4 implementation on X11:
Did nothing when QApplication::flush() was called (the flush()
overrides in {unix,glib} event dispatchers with empty bodies).
In Qt5 this function somehow has been repurposed (inconsistently)
to do what QCoreApplication::sendPostedEvents already does:
QAbstractEventDispatcher::flush() = 0;
=> QCocoaEventDispatcher::flush() {}
=> QEventDispatcherCoreFoundation::flush() {}
=> QIOSEventDispatcher (does not override ::flush())
=> QEventDispatcherGlib::flush() {}
=> QPAEventDispatcherGlib (does not override ::flush())
=> QEventDispatcherUNIX::flush() {}
=> QUnixEventDispatcherQPA (when QT_NO_GLIB=true)
::flush() { if (qApp) qApp->sendPostedEvents(); })
==> QAndroidEventDispatcher (does not override ::flush())
=> QEventDispatcherWin32::flush() {}
=> QOffscreenEventDispatcher::flush() {

QEventDispatcherWin32::flush();
}

QEventDispatcherWinRT::flush();
}
=> QWinRTEventDispatcher (qminimaleglintegration.cpp) (does not override ::flush())
=> QWinRTEventDispatcher (qwinrteventdispatcher.h) (does not override ::flush())
Whatever this function was doing on macOS in Qt3 and Qt4 also has been
dropped in Qt5. It appears that the other event dispatchers in Qt5 that
have overrides for flush() have simply copy-pasted this logic.
Clearly the documentation of QCoreApplication::flush() is outdated and
has nothing to do with the actual implementation in Qt5.
This function is rarely used in Qt5 sources. It should be safe to remove
the calls to QCoreApplication::flush() from Qt source code, as this
function has been doing nothing on most platforms anyways. Repurposing
it even broke handling of posted events (see QTBUG-48717).
[ChangeLog][QtCore][Event loop] QCoreApplication::flush() is now
deprecated. Use QCoreApplication::processEvents() and
QCoreApplication::sendPostedEvents() instead.

This worked well for cases of #ifdef Q_DEAD_CODE_FROM_QT4, but less so
for cases of #ifndef Q_DEAD_CODE_FROM_QT4, where the code was actually
unconditionally included.
To make this even clearer, the defines have been replaced by checks for
1 or 0, with a comment describing how the code used to look in Qt4. The
use of constants in the check also makes it easier for editors to parse
the condition and show visually that the code is defined out.
