Excuse me, but I was too brief.
I mean your lexize method of dictionary should return pointer to array with 3
elements:
first should points to "one" C-string, second - to "hundred" C-string and 3rd is
NULL.
Array and C-strings should be palloc'ed in short-lived context, because it's
lives during parse text only.
