Your name : Bernie Huang
Your email address : Bernie.Huang@ec.gc.ca
System Configuration
---------------------
Architecture (example: Intel Pentium) : Intel PIII
Operating System (example: Linux 2.0.26 ELF) : RH Linux 6.2
PostgreSQL version (example: PostgreSQL-6.5.1): PostgreSQL-7.0
Compiler used (example: gcc 2.8.0) : Don't know
Please enter a FULL description of your problem:
------------------------------------------------
When you inherit table B from table A, the primary key in A won't be
inherited to B, but only the columns.
I was wondering how do you inherit a primary key or, even, a foreign
key? If it's not possible, what are the ways going around it? (not
null index or...???)
Thanks for your help!

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
CREATE TABLE parent (
col1 INT4 PRIMARY KEY,
col2 text);
CREATE TABLE child (
col3 text) inherits (parent);
CREATE TABLE foreign_to_child (
col1 INT4,
FOREIGN KEY (col1) REFERENCES child
ON UPDATE CASCADE
ON DELETE SET NULL);
If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------
I tried using not null index on the column that's supposed to be the
primary key in the child table, but failed to work.
