Hi

I was tracing a simple SELECT query to find how pg works for fetching tuples.
but I'm totally lost in the code.
Could you help me to understand under the hood?
I know about parsing and planning parts, my actual problem is executer.
If you show me a road map to study, I would appreciate it.

Regards
Soroosh
