Subject: [PATCHES] psql - \dt,\di commands.

I sent this a couple of months ago in re a request by Maxim
Kozin, but I had the patch reversed, creating some confusion
over applying it.

Here's a more complete version.

Adds \dt to list only tables/views and \di to list only
indicies.  \d will still work as before.
