The bootstrap parser is using only in bootstrap mode, which is when the template1 database is initially created. It has a completely different syntax than the main parser. If what you are looking for is to implement a new command or modify an existing one, ignore the bootstrap parser. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc. ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
