psql question

Hello,

I've been searching off-and-on for an answer to this question, but I haven't
found anything but fleeting references.

Here's the problem/question:

On machines where I've installed PostgreSQL 7.0.2 from RPM, psql allows use
of the up arrow key for history and the escape/tab key for command
completion, but on my remote web host (webpipe.net) those keys don't work.
What do I need to do to get these features working on my remote web host?
I've seen reference to .psqlrc in the psql man file, but not much else (no
syntax, etc).

Thanks in advance!

Joe
