Where Stephan found it?
https://github.com/postgres/postgres/blob/master/src/backend/parser/gram.y
But given that you have the LALR postgres grammar
in the source code
of postgres?
Where? Because I'm interested.
I had a look. It's long (14000 lines) but there is a bit of noise in
there (semantic actions and support functions).
It's nice, well commented and the layout is very clear. Probably the
nicest I've come accross.
The other key to check is the lexer. One can hide a lot of complexity
inside the lexer (R, I'm looking at you!).
