If you ever have the need to generate an encrypted password to put it into scripts or anything else, then you can use the following SQL command to generate it:

select 'md5'||md5('password'||'rolename');

or in shell

echo -n 'passwordrolename' | md5sum | awk '{ print "md5" $1 }'

Important is, that your rolename is appended to your password and this construct then put into md5. The important piece in the source is pg_md5_encrypt()
