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.
