pg_get_serial_sequence and table inheritence
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!

You have one sequence for every serial field in sequences (from psql: "\ds").

Sorry, I should have searched before posting, I started a new thread.
Please refer to my solution posted today as "pg_get_serial_sequence and
inheritence" (remarkably similar to yours! although mine was less
accurate ;-)
