pg_get_serial_sequence and table inheritence - Mailing list pgsql-general

Is there anything similar to pg_get_serial_sequence that will work
with tables that have an inherited serial column?  For example, if I
have 2 tables:

create table base (
id    serial not null primary key
);

and

create table derived (
stuff    text,
constraint derived_pkey primary key(id)
) inherits (base);

I'd like to be able to call pg_get_serial_sequence passing "derived"
for the table and "id" for the sequence column (to get, in this case
"base_id_seq").  If nothing like this currently exists, any
suggestions on how I could write a plpgsql function to get this
behavior?

Thank you for any suggestions!
