Are you basing this on your earlier comment:

"
Or maybe look at it this way:
create table test1 (a int4);
create table test2 (b int4) inherits (test1);                   ^ col #1          ^ col #2
alter table test1* add column c int4;                             ^ col #3

"?

If so, I thought Oliver pointed out that you had the numbering wrong.
I thought so, too...

Which is right?
