This would be:

\set AUTOCOMMIT off
DROP TABLE foo; -- error, rolled back
CREATE TABLE foo ...
COMMIT;

You could as well do:

\set AUTOCOMMIT on -- default
DROP TABLE foo; -- print error message
CREATE TABLE foo ...

There is not much difference, except for locking, ok. I see your point, but 
I don't think this makes enabling it by default (even in .psqlrc) any safer.
