[developers] Setting LKB lexicon to LexDB

[Joshua Hou]

Hello Developers,

I have not yet succeeded in getting my TDL lexicon into LexDB dump
format, but I added a couple lexical entries to LexDB manually to see if
I could get LKB to use a LexDB lexicon.

I have the following line set in lkb/globals.lsp:

(defparameter *psql-lexicon-parameters* '(:db "lil" :user "lexdb"))

The following is set in lkb/script:

 ;; optionally, use a lexical database; 
  ;; to activate the DB set *psql-lexicon-parameters* (see globals.lsp)
  (if *psql-lexicon-parameters*
    (load-psql-lexicon-from-script)
    (read-cached-lex-if-available
     (list
      (lkb-pathname (parent-directory) "lexicon.tdl")
      )))

The above were set as per instructions in the "HOW TO set LKB lexicon to
LexDB" section of this tutorial: 
http://wiki.delph-in.net/moin/Initialize_LexDB

However, I'm getting the following error when I try to load my grammar:

Error: attempt to call `LOAD-PSQL-LEXICON-FROM-SCRIPT' which is an undefined
       function.
  [condition type: UNDEFINED-FUNCTION]

I have grepped through both the logon tree and my grammar recursively
for "load-psql-lexicon-from-script", but have not found anything.  Does
anyone know where this function should be defined?

Thanks so much,

Joshua
