From c65ea0e040f08b59407cd74f8f0f0dd190169d46 Mon Sep 17 00:00:00 2001
From: Bruce Momjian <bruce@momjian.us>
Date: Fri, 16 Jan 1998 23:21:07 +0000
Subject: New pg_attribute.atttypmod for type-specific information like varchar
 length.

Cleans up code so attlen is always length.

Removed varchar() hack added earlier.

Will fix bug in selecting varchar() fields, and varchar() can be
variable length.
