The Momjian books shows this:
test=> CREATE TABLE parent_test (col1 INTEGER);
CREATE
test=> CREATE TABLE child_test (col2 INTEGER) INHERITS
(parent_test);
CREATE
test=> \d parent_test
Table "parent_test"
Attribute | Type | Modifier
-----------+---------+----------
col1 | integer |
test=> \d child_test
Table "child_test"
Attribute | Type | Modifier
-----------+---------+----------
col1 | integer |
col2 | integer |
but I think it would be very important, to know inheritance as to
know indexes.
