Well, changing '&&' to '||' breaks the stated comment of the patch, namely:         /* must not match CREATE TRIGGER
...EXECUTE PROCEDURE */ 

I assume this is an accepted quirk of previous_word() since we have
this existing similar code:

/* DROP, but watch out for DROP embedded in other commands */   /* complete with something you can drop */   else if
(pg_strcasecmp(prev_wd,"DROP") == 0 &&            pg_strcasecmp(prev2_wd, "DROP") == 0) 

and the patch does seem to auto-complete a beginning EXECUTE
correctly. We could probably use a comment somewhere explaining this
quirk.
