I saw a note a few days ago about the arrow keys not working in psql in
7.0. As I recall the answer was to make sure the configure script could
find "readline.h". I had the same problem as the original questioner,
and attempted the suggested fix. The fix did allow configure to find
"readline.h" as well as "readline/readline.h", but the problem wasn't
fixed. After some investigation (i.e. reading the source), I determined
the real problem was my version of readline.
It *appears* to me that 7.0 requires readline version 4.1 in order for
the readline history features to work, whereas 6.5.3 was happy with an
earlier version. When I updated my version of readline, the readline
history functions started working.
I hope this isn't a repeat of earlier mail on this topic (I only joined
the mailing list about a week ago), and I hope it helps people with the
same problem that I had.
