Re: attislocal value changed with the dump

This is the repro with the sql file below.

createdb bug1
psql bug1 < qna.sql
pg_dump bug1 > bug1.sql
createdb bug2
psql bug2 < bug1.sql

psql bug1
=# select r.relname, attname, attislocal, attinhcount from pg_attribute a join pg_class r ON (a.attrelid = r.oid) where attname = 'avid' order by relname;
...output omitted...
=# \c bug2
=# select r.relname, attname, attislocal, attinhcount from pg_attribute a join pg_class r ON (a.attrelid = r.oid) where attname = 'avid' order by relname;
...output omitted but shows all columns as local...

I'm running 8.0.4 by the way.

The problem may be with the addition of
default values and indexes on the inherited
columns. It may assume that because we
are altering the column and/or adding an
index on the inherited columns then the
column is local.
