While I've not looked too closely, I suspect this might be due to the FORMAT_LA hack in base_yylex: /* Replace FORMAT by FORMAT_LA if it's followed by JSON */ switch (next_token) { case JSON: cur_token = FORMAT_LA; break; } So if you are writing a production that might need to match FORMAT followed by JSON, you need to match FORMAT_LA too. (I spent a little bit of time last week trying to get rid of FORMAT_LA, thinking that it didn't look necessary. Did not succeed yet.) regards, tom lane
