My first recommedation is to update your PostgreSQL version to 9.0 and later you can use the PgPool-II version 3.0 in order to use the Hot standby/Streaming Replication features with it.
Here is a example of the configuration of PgPool-II 3.0.1 and PostgreSQL-9.0.2 http://lists.pgfoundry.org/pipermail/pgpool-general/2011-February/003338.html Regards -- Ing.
