This is a neat idea, but there are some issues.

- There's a new GUC.  This is probably not compelling enough a feature for that.

- The check, if I understand correctly, is only done on connect, even though it
  could change during a session.

How about something that:

- Allowed setting a query to be executed after each command.

- Put the results of that query into a psql variable.

This differs from \gset in that it would be executed silently at the
end of each command.

What say?
