Password authentication disabled due to MD5 usage

Hello,

since I upgraded PostgreSQL it now stores passwords in MD5 format. When
I try connecting using password authentication, i get:

Jan  9 12:22:24 prometheus postgres[28540]: [2] LOG:  Password is stored
MD5 encrypted.  'password' and 'crypt' auth methods cannot be used.

Now, if password and crypt are no longer available, how am I supposed to
connect through TCP at all? Assuming I don't want to set up kerberos or
something just to get PostgreSQL working :)

The the more important question is, how do I change this back? In the
current situation I couldn't care less about this type of security
because everything is done on the loopback interface so plain text is
fine. I just need to be able to connect using password authentication
(I'm using JDBC).

Any pointers are greatly appreciated. Thanks!
