Summary: adding column to table w/ index causes column not to be seen

System Configuration
--------------------
  Operating System   : Solaris 2.6

  PostgreSQL version : 6.4.2

  Compiler used      : SunCC 4.2

Hardware:
---------
SunOS fondue 5.6 Generic_105181-12 sun4m sparc SUNW,SPARCstation-20
	

Versions of other tools:
------------------------
flex 2.5.4

--------------------------------------------------------------------------

Problem Description:
--------------------
It seems that if a column is created in a table with an existant index,
and an attempt is made to use that index, the backend doesn't
see the new column.

--------------------------------------------------------------------------

Test Case:
----------
The following SQL illustrates the problem:

======================================
drop table snafu;
create table snafu ( a1 text, a2 text );
insert into snafu values ( 'snark', 'fido' );
create index snafu_i1 on snafu using hash ( a1 );
alter table snafu add column a3 text;
update snafu set a3 = 'snzay' where a1 = 'snark';
=========================================

This results in

drop table snafu;
DROP

create table snafu ( a1 text, a2 text );
CREATE

insert into snafu values ( 'snark', 'fido' );
INSERT 156996266 1

create index snafu_i1 on snafu using hash ( a1 );
CREATE

alter table snafu add column a3 text;
ADD

update snafu set a3 = 'snzay' where a1 = 'snark';
ERROR:  Relation snafu does not have attribute a3

Removing the "create index ..." line causes the problem to
go away.
