The PostgreSQL Global Development Group is the collective project attribution used for the development and documentation of PostgreSQL, an open-source database management system. Its documentation specifies concrete behavior for database transactions, database integrity constraints, database query operations and storage mechanisms; these specifications are more precise than inferring behavior from SQL syntax alone.[ref]
For example, PostgreSQL documents transaction isolation levels in terms of visible snapshots and permitted anomalies. The project name here identifies the responsible development community, rather than one individual author or a separate database product.
