inheritance/oid questions
Suppose I have table a and b (b inherits a).
Then I do select * from a*;
Now, I'd like to know which table this particular row came from (a or b).
Is this possible? Or do I have to have a column where I'd store what kind
of object this is?

In the up and coming version of postgres there will be a special column
called "tableoid" which gives the oid from pg_class of the table it came
from. If you are not using the current CVS sources, you will have to
keep a column updated yourself.
