The client can say "SET autocommit to off" or on. It can use SHOW to
to see the setting. Environment variables are used mostly for
connecting, and once connected, we use GUC.
In fact, an environment variable seems wrong because it isn't integrated
into the client, like a SET command is.

True, but GUC seems like the way to go, and we have per-user/db settings
