Bug found in psql interface

Short Description
Inconsistency in the way that psql handles long names

Long Description
PostgreSQL version 7.1.3
OS: RedHat Linux 6.2

I compiled this version of postgresql from source, with the NAMEDATALEN
variable set to 512. All works ok, apart from when I use
the psql interactive terminal, and type:

\d City_setregions_bds_regions_ass_rel

at the command line, where City_setregions_bds_regions_ass_rel is the
name of a table that exploits the longer names. The terminal reports:

Did not find any relation named "city_setregions_bds_regions_ass_".

It therefore looks like the \d command is not picking up the longer
NAMEDATALEN at compile time.
