I was unable to parse a comment in src/backend/parser/gram.y around line 11364:
/*
* As func_expr but does not accept WINDOW functions directly (they
* can still be contained in arguments for functions etc.)
* Use this when window expressions are not allowed, so to disambiguate
* the grammar. (e.g. in CREATE INDEX)
*/
Maybe "but" is unnecessary in the first sentence in the comment?
Best reagards,
