psql history buffer.

Hi,

I have compiled postgres on a few different Linux boxes (all Red Hat
i386).

My question is regarding the psql program, on some of the machines
up/down cursor lets me scroll back and forth through the history buffer,
on other machines this luxury is gone and an up cursor results in.

template1=> select date('now');
date
----------
01-01-2000
(1 row)

template1=> ^[[A

Why is this?

Are there any libraries required by pgsql that maybe are present on some
machines and not others hence the different behaviour?

Thanks,

Nigel Tamplin.
