Checkout from HEAD this morning, no modifications. Did make
distclean and fresh build to ensure no problems caused by mixed
build. 32 bit kubuntu on single drive dual core workstation. Fresh
initdb. Default configuration.
postgres=# create database bug;
CREATE DATABASE
postgres=# \c bug
You are now connected to database "bug" as user "kgrittn".
bug=# create table person (namel text not null);
CREATE TABLE
bug=# create table t (id int primary key) inherits (person);
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index
"t_pkey" for table "t"
CREATE TABLE
bug=# create or replace function sname(person) returns text
bug-# language sql immutable as $$select upper($1.namel)$$;
CREATE FUNCTION
bug=# create index t_sname on t (sname(t));
CREATE INDEX
bug=# select oid, relname from pg_class
bug-# where relname in ('person','t');
oid | relname

16391 | t
(2 rows)

DROP TABLE
[so far, behavior is as expected]

All is fine if the t_searchname index is left out or the t table
defines all columns directly rather than inheriting them from
person. Similar failure if person is dropped first or on the same
statement as t.
