Features We Do _Not_ Want

=========================

* All backends running as threads in a single process (notwant)

* All backends running as threads in a single process (notwanted)

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 (notwant)

* Optimizer hints (notwanted)

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.
