Having a session settings in a database that heavily multiplexes
requests over the same connection is a bad idea: the features simply don't work
together. A concurrent statement may tweak the setting while the
previous statement is still in progress.

Having this feature is simply a time bomb waiting to explode:
sooner or later there will be a setting that makes sense to change
asynchronously and that impacts in-flight transactions, and there
will be no sane fix in sight.
