Features We Do _Not_ Want
=========================
* All backends running as threads in a single process (not want)
* All backends running as threads in a single process (not wanted)
This eliminates the process protection we get from the current setup.
Thread creation is usually the same overhead as process creation on
modern systems, so it seems unwise to use a pure threaded model.
* Optimizer hints (not want)
* Optimizer hints (not wanted)
Optimizer hints are used to work around problems in the optimizer. We
would rather have the problems reported and fixed.

* Allow AS in "SELECT col AS label" to be optional (not wanted)
Because we support postfix operators, it isn't possible to make AS
optional and continue to use bison.
