   Seems strange.  Did you re-run PG's configure after installing libreadline?
   Are you sure that the include (.h) files found by configure match the
   library (.a or .so) file?

   It seems there were some incompatible changes in readline 4.2.  Use
   version 4.1 until we have a fix.

   The essence of the problem seems to be in the following lines of
   readline.h that comes with libreadline 4.2 (/usr/include/readline/readline.h):
   
   Line 415-429
   
   #if 0
   /* Backwards compatibility (compat.c).  These will go away sometime. */
   extern void free_undo_list __P((void));
   extern int maybe_save_line __P((void));
   extern int maybe_unsave_line __P((void));
   extern int maybe_replace_line __P((void));
   
   extern int ding __P((void));
   extern int alphabetic __P((int));
   extern int crlf __P((void));
   
   extern char **completion_matches __P((char *, rl_compentry_func_t *));
   extern char *username_completion_function __P((const char *, int));
   extern char *filename_completion_function __P((const char *, int));
   #endif
   
   
   
   And the fix to make it compile is the following:
   
   src/bin/psql/tab-complete.c
   
   Line 64:
   
   char     *filename_completion_function(char *, int);
   
   should read
   
   char       *rl_filename_completion_function(char *, int);
   
   
   Readline continued to work for me after having upgraded my Debian to
   the latest unstable release (which apparently contained alse libreadline
   4.2) and patching the tab-complete.c file.
   
   Sorry for the "pseudodiff" but hopefully it gives a clue. Since I do not
   know much about libreadline and its history I hope someone else will
   tell how the actual patch should look like (so it would work with older
   versions).
