Log message:
    Change case-folding of keywords to conform to SQL99 and fix misbehavior
    in Turkish locale.  Keywords are now checked under pure ASCII case-folding
    rules ('A'-'Z'->'a'-'z' and nothing else).  However, once a word is
    determined not to be a keyword, it will be case-folded under the current
    locale, same as before.  See pghackers discussion 20-Feb-01.
