> jdbc:postgresql://localhost/5433/wonderbook

if you want to include a port in a URL, you precede it with a colon   
localhost:5432

however assuming the database you want to connect to is called 'wonderbook' 
then the uri is;

jdbc:postgresql://localhost/wonderbook   or

jdbc:postgresql://127.0.0.1/wonderbook


you don't add the port here. you must make sure that pg_hba.conf shows:

# IPv4 local connections:
host    all             all             127.0.0.1/32            trust

basically saying that if anyone from the localhost machine tries to connect, 
let it and trust the connection. I just checked my postgresql.conf file and I 
see the line:

#listen_addresses = 'localhost'         # what IP address(es) to listen on;

is commented out so this is the default (to listen on localhost).
