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?
