No, this is part of the solution. :) Across various versions of readline
the header files are either #include <readline.h> or #include
<readline/readline.h>, apparently for you the latter is the case.

I'm amazed that this won't enable readline support in psql. You can look
at src/include/config.h if the corresponding macros are defined
(HAVE_READLINE_READLINE_H and HAVE_LIBREADLINE). The other end of this is
src/bin/psql/input.[hc], perhaps you want to run the .c through the
preprocessor and see what happens. What readline version do you have? Did
it work in 6.5.*?
