Description:
It appears that the bug discussed here has regressed since 9.1:

Context information: the bug breaks Londiste, which uses
pg_attribute.attname to match columns on the primary key index with the
corrisponding columns on the table.
I found the bug after a customer reported Londiste issues on a table whose
primary key had been renamed.
