Sirix is a versioned tree-based storage system. It provides Snapshot Isolation through MVCC and is best suited for flash-based storage. The tree encoding is suited for heavy update operations. It provides diffing algorithms either to import diffs between currently shredded (imported) XML documents to update a tree structure or to get the differences between versions of a tree structure. A GUI provides several visualizations for comparing imported tree structures.
Porte is a framework designed to save time and to simplify the development of relational database applications written in PHP. It saves you from writing repetitive SQL to interact between your objects and the database. It can retrieve, search, and save objects without a single line of SQL.
mylbhelper helps dumb load balancers do their job. It monitors a local MySQL instance by periodically issuing a query. Should the query fail, a custom script, which typically would firewall off the load balancer, is executed. Likewise, when it comes back up, another script is executed. This means you can use any load balancer capable of distributing TCP traffic rather than one natively capable of talking MySQL. mylbhelper can also act solely as a monitoring daemon.
pg_greentrunk provides fundamental components of GreenTrunk, an interface protocol (API) for using a PostgreSQL database with Python. It provides an interface for implementations to use, and provides documentation in the form of Python modules to allow immediate access to object descriptions, even when inside a Python console.
pg_pqueue is a Python package that provides low-level PQ protocol classes for interacting with a PostgreSQL database. It supports version 3.0 of the protocol. The package also provides a basic protocol transaction class. This class keeps the state of the protocol in an interrupt safe manner, and validates the integrity of the communication as messages are received. In general, you probably will never use this package directly, unless you are writing a driver.
finic helps users manage their finances. It can be used on a local network (as a client-server system for many users) or on local computer (client only for one user), with separation of accounts, clauses, and customers. It can encrypt information and manage different users with different access rights. Reports can be generated as HTML, PDF, or XLS files or through an internal print preview system. An API is available for creating extensions.
Cybercluster is a multi-master replication solution. Cybercluster has no single point of failure, an integrated load balancer, an integrated replication server, a monitoring server (to track replication), a consistency checker, an optional 2 Phase Commit for cluster-wide writing, support for all PostgreSQL features. Cybercluster is easy to setup. In contrast to many other solutions, Cybercluster is built on top of the PostgreSQL core and has full access to PostgreSQL internals. Cybercluster is heavily based on the concepts of PGCluster.
