I'm not in the mood to dig through that bash function of yours to
figure out where that error message is coming from... but I'm betting
your problem is because the createuser command you used didn't specify
the "--login" option. The pg_user view only shows those users able to
login.
To double check, try this command:
SELECT rolcanlogin FROM pg_authid WHERE rolname = 'laurent';
from the psql client. I'm betting you'll see 'f' for false. To fix, try:
ALTER ROLE laurent WITH LOGIN;
