I'll be happy to add in anything I've missed.
The Postgres grammar classifies keywords in one of several lists, in order to make them available as names to users (column names, function names, etc). So each time you create a new keyword and add it to the keywords.c list, you have to add it to one of the lists on gram.y too. See gram.y line 7669 ff.
