Hi:

I posted this in pgsql-general last week, but I got no answer. Maybe I
have better luck this time?

TIA.

Subject: [GENERAL] DROP TABLE, and children?

Hi:

If I'm creating some inherited tables from a parent,

rwtest=> CREATE TABLE test (col1 INTEGER);
CREATE
rwtest=> CREATE TABLE testchld () INHERITS (test);
CREATE

 and then try to drop the parent, it says

rwtest=> DROP TABLE test;
ERROR:  Relation '22057' inherits 'test'

Is there some easy way to DROP all children tables? I was looking
through some old archives, I found that neither UPDATE nor DELETE dealt
with inheritance (some grammar that had to do with relation_name rather
than relation_expr), but couldn't find anything about DROP.

Maybe some query to get all relations that inherit from the one I'm
trying to drop?

TIA.
