You're creating an insertString with the literal words "username" and
"password" in them. This is a java issue, not a PG issue. You'll want
something like (sorry if syntax is wrong, but I don't do Java):
String insertString = "Insert INTO ... VALUES ('" + sql_escaped(username) +
"')..."
You *will* want to escape the username and password otherwise I'll be able to
come along and insert any values I like into your database. I can't believe
the JDBC classes don't provide
1. Some way to escape value strings
2. Some form of placeholders to deal with this
