Hello,
I'm trying to figure out if this is a bug or a feature.
Two child tables, one created with inheritance, one altered to have
inheritance:
create table A(a text, b text);
create table A1() inherits (A);
create table A2(a text, b text);
alter table A2 INHERIT A;
When you drop a column from the parent table only the tables CREATED with
inheritance drop the column:
alter table A drop column b;
\d A1
Column | Type | Modifiers
--------+------+-----------
a | text |
Inherits: a
\d A2
Column | Type | Modifiers
--------+------+-----------
a | text |
b | text |
Inherits: a
Is this intended behavior? I have postgres 8.2.9.
-Caleb
