I think you need better tools to guide you in exploring the source code. For example, you can use cscope to tell you where is CreateTrigStmt used, and you would find gram.y; and use it to tell you where CreateTrigger is used, and you would find utility.c.
Thanks for your advice. I was relying on PostgreSQL documentation which was quite helpful so far. Let me try some development tool.
Any half-decent code editor should be able to generate a "database" of symbols and let you frolic around the various files quickly. Without that, anyone would be completely lost in developing new features of even the lowest complexity.
