I don't think plugging in localhost will work for a jdbc connection
reference. Try something like

jdbc:postgresql://server:port/dbname

that should do the trick (read: worked for me)

though I am having some other issues with DbVisualizer concerning
jdk/jdbc conflicts of some sort. Assuming you get connected you can
check out the thread in the pgsql-jdbc list.
