Body of first available message related to this bug follows.

The following bug has been logged on the website:

Bug reference:      15962
Logged by:          Steven Morris
Email address:      (redacted)
PostgreSQL version: Unsupported/Unknown
Operating system:   PostgreSQL 9.3.9 on x86_64-unknown-linux-gnu, com
Description:        

I had a table that was defined as ''search_id serial NOT NULL'' which
apparently hit the value limit for ''integer'' 
Rather than changing the original table from serial/integer To bigint in
case that was not the issue,
 I renamed the table and created a new table using ''bigint'' using the same
sequence name like so.. which did work

search_id bigint NOT NULL DEFAULT
nextval('d2_search_history_search_id_seq'::regclass)

But now we have determined that the old/original table/data was no longer
needed and it could be dropped BUT when doing so I got the 

ERROR:  cannot drop table d2_search_history_2019050 because other objects
depend on it
DETAIL:  default for table d2_search_history column search_id depends on
sequence d2_search_history_search_id_seq
HINT:  Use DROP ... CASCADE to drop the dependent objects too.
********** Error **********
ERROR: cannot drop table d2_search_history_2019050 because other objects
depend on it
SQL state: 2BP01
Detail: default for table d2_search_history column search_id depends on
sequence d2_search_history_search_id_seq
Hint: Use DROP ... CASCADE to drop the dependent objects too.

So at this point I tried changing it by several ways like below but it still
is insisting that it cannot be dropped without cascade.
I do Not want to drop the sequence since I defined the newer table to use
it.
--CREATE SEQUENCE public.tmp_seq;
--ALTER TABLE public.d2_search_history_20190520   ALTER COLUMN search_id SET
DEFAULT nextval('tmp_seq'::regclass);
--ALTER TABLE d2_search_history_2019050  DROP CONSTRAINT
d2_search_history_pkey;
--ALTER TABLE d2_search_history_2019050 DROP COLUMN search_id;
ERROR:  cannot drop table d2_search_history_2019050 column search_id because
other objects depend on it
--ALTER TABLE d2_search_history_2019050   ALTER COLUMN search_id DROP
DEFAULT;

Looking at the properties of the sequence I still see it tied to the older
table 
Column	d2_search_history_2019050.search_id	auto
Column	d2_search_history.search_id	normal

Any suggestions on how to remove the dependency it still has ?  or will I
have to make a New sequence for the new table and call it ?
