Hello Andres !

Another way that I tested and it's working is to use https://www.bottlecaps.de/convert/ paste the postgresql grammar there and press "convert" and after press "view diagram".

Again optionally manually add the Tokens to a better diagram !

====

// Tokens from postgresql-13.3/src/include/parser/kwlist.h

ABORT_P ::= "abort"
ABSOLUTE_P ::= "absolute"
ACCESS ::= "access"
ACTION ::= "action"

...

====

Cheers !

It'd be nice if you could share that tool. The diagrams this can generate
are neat...
