If you install the readline development files (ie. rpm -i
readline-devel-version.rpm or use YAST or whatever is appropriate for
your distro) then you won't get this error. It basically only affects
command editing and history in psql.

And had you run /usr/local/pgsql/bin/pg_dump it would have worked fine
as well. But /usr/local/pgsql/bin is probably not in your $PATH at all
let alone existing ahead of /usr/bin so just running pg_dump loaded the
incorrect version.

My quick-n-dirty "fix" is to make symbolic links in /usr/bin for all pg
programs:

cd /usr/local/pgsql/bin
for x in * ; do ln -s /usr/local/pgsql/bin/$x /usr/bin/$x ; done

But be sure to remove the out-of-date version first.

Cheers,
Steve
