Save a minor detail.  It would be

begin;savepoint;    select 0/0;  -- abort    savepoint;  -- commands will be ignored    select 1; -- commands will be
ignored   release; -- commands will be ignored    release; -- commands will be ignored
 
commit; -- abort message

Note that I'm trying to tell you something with the indenting; all those
commands are inside one and the same subtransaction.

And I'm not planning to do anonymous savepoint.  Do these buy us
anything?
