The following bug has been logged on the website:
Bug reference: 15853
Logged by: wondertx
Email address: wondertx(at)gmail(dot)com
PostgreSQL version: 11.3
Operating system: Arch Linux
Description:
The following SQL executed will drop the sequence `t_id_seq`:
CREATE TABLE t(id SERIAL, value INT NOT NULL);
CREATE TABLE t_bak LIKE t INCLUDING DEFAULTS INCLUDING INDEXES INCLUDING
COMMENTS INCLUDING CONSTRAINTS);
DROP TABLE t CASCADE;
This will drop default value of column `value` in t_bak.
However, the following SQL will not drop the sequence:
CREATE TABLE t(id SERIAL, value INT NOT NULL);
DROP SEQUENCE t_id_seq;
CREATE SEQUENCE t_id_seq;
ALTER TABLE T ALTER COLUMN ID SET DEFAULT NEXTVAL('t_id_seq'::regclass);
CREATE TABLE t_bak LIKE t INCLUDING DEFAULTS INCLUDING INDEXES INCLUDING
COMMENTS INCLUDING CONSTRAINTS);
DROP TABLE t CASCADE;
