The point IIRC was to be able to remove stuff that required type Datum to be defined: -extern void ShutdownXLOG(int code, Datum arg); which led to the idea that the new header would be about process control for xlog.c. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
