Sun Cluster HA for PostgreSQL requires a database to which it can connect and where it can manipulate a table for monitoring purposes. The password policy of this database for access from the localhost must be either trust or password. All other password policies can be whatever is applicable. For more information about setting the password policy, see Registering and Configuring Sun Cluster HA for PostgreSQL. For more information about the password policy, go to http://www.postgresql.org.
