PostgreSQL has shipped with an integrated standby features since its version 8.2. This allows creating a master/standby pair of nodes, where the standby regularly receives a log of database updates from the master.
While the main components of the feature are included with PostgreSQL, the user is expected to provide many scripts to handle tasks such as copying files between master and standby.
2warm makes this easy and robust. It provides scripts to accomplish all of the necessary steps in the most common configuration, where ssh is used as the way to communicate between the master and standby. It also provides a set of management tools for easily setting up both sides of a warm standby pair, and dealing with state transitions as nodes are brought up, are taken down, or fail.
Full documentation is available in the docs/ subdirectory, written in ReST markup. Tools that operate on ReST can be used to make versions of it formatted for other purposes, such as rst2html to make a HTML version or rst2pdf for PDF. The documentation is currently available in English and Italian.
