Yes, this is what confused me for a while. Configure found readline.h,
readline/readline.h and -lreadline, but it didn't find readline/history.h.
So readline was configured and actually used (I walked through
src/bin/psql/input.c to make sure), but the history features were not being
used. So I could edit the current line, but I couldn't go backwards in
history. Evidently the version of readline that I had installed didn't
contain a history.h file (although it did find the using_history entry
point in the library), and this caused configure to disable the history
features?
