    this patch solve 2 problemes : · fdb37f07
    Bruce Momjian authored
    probleme number 1 :
    
    - configure can find the library readline , but don't
      find the header file . so in this case we don't use lib readline
      .
    
    probleme number 2 :
    
    - when you have postgres 6.2.1 and readline installed
      with the same prefix( and generally all your software ) .  you
      can compile the version 6.3 .  I use this prefix , when configure
      ask me for "Additional directories to search for include files"
      .
    
      ( because there a conflict in the header when you
        compile psql.c ) In this case, you must permut the sequence of
      directive -I .
