Re: JDBC driver problem ? - Mailing list pgsql-jdbc

Looking at the source code for 7.2.1, which is what I have here, it
looks like the driver supports the 'password', 'crypt', 'md5' and of
course, 'trust' authentication schemes. Try using
DriverManager.setLogStream(System.out) before getting the connection,
the driver should print the auth scheme to System.out.
