PostgreSQL version 8 offers a "Point In Time Recovery" mechanism
whereby you archive the WAL files; the WAL files represent incremental
backups.
Slony-I 1.1 provides a new "log shipping" feature where you can
archive incremental changes, too; it tries to support versions as far
back as 7.3.3, so it might be compatible with your needs...
