To me, that seems like a better approach, although it's a little hard
to see how we'd address Alvaro's desire to have it roll back
automatically when the session disconnected.  The disconnect might be
caused by a FATAL error, for example.

I'm actually all in favor of doing more things via SQL rather than
configuration files.  The idea of some ALTER SYSTEM command seems very
compelling to me.  I just don't really like this particular
implementation, which to me seems far too bound up in implementation
details I'd rather not rely on.
