pg_xnode is an extension (module) which adds several data types to the PostgreSQL database server, allowing it to store XML documents, XML (tree) nodes, and XPath expressions. Unlike the in-core implementation of XML, pg_xnode does not require repeated parsing of XML data, and thus should be more efficient. In addition, the extension has functions to add/remove nodes to/from existing XML documents, and templates to create XML documents from tables.
PHPG is a PostgreSQL database interface class that was specifically designed to confront and resolve the majority of the long-standing issues with PHP's native PostgreSQL driver.
