Hello!

steb by step:

first i open psql using the superuser (postgres), and writing:
=> create database test;
=> create user tester with password 'tester';
=> ^d
in the shell writing:
$ psql -d test -U tester -f ss3.sql
$ psql -d test -U tester
now i am back in the psql shell again, write:
=> \i test5a.sql
<BEGIN> 
<SELECT>
=> fetch 1 in lionhart;
=> fetch 1 in lionhart;
=> fetch -1 in lionhart;
=> fetch -1 in lionhart;
=> fetch 1 in lionhart;
*** last fetch should return a row, but it doesn't seem like...
