Description:

Hello dev, sorry for my english i'm a french GIS user.
I'm actually using PostgreSQL with Postgis in an intership and if I don't do
mistake, I have discover the command INHERITS don't work as we would.
I have done a test with the exemple in the documentation with my data base.
The command gives all columns from the parent table (cities in the exemple)
to the child table ;  but attributs aren't given with tables to the child as
we would.
And more strange, if I create attributs by the child table, these attributs
are given to the parent table...
I have already used the Inheritance command before and it was normaly
working.
I don't know if someone have seen the same bug, and I hope I wasn't wrong
and that was normal.
Sorry for possible mistakes and I stay available if you need more details.
Have a good day.

Yes, providing the code that demonstrates the bug you are reporting is basically a requirement for reporting bugs.

Based upon an off-list reply I've determined there is no bug here.

Please explain what you mean by "attributes".  Most people here
consider "attribute" to be a synonym for "column", but I noticed that
you used both the terms in your first email as if you meant two
different things.

It helps if you show the exact commands you run (to create the
parent/child tables in an empty database), the output you get, and
explain how that output differs from the output you expect.
