哪個是

1）重命名從episode_id_seq該序列的最佳方式sequence_id_seq

2）重命名SEQUENCE_NAME的值從episode_id_seq到sequence_id_seq

3）重命名從episode.id所擁有的價值到sequence.id

test777=# \d episode_id_seq 
    Sequence "public.episode_id_seq" 
Column  | Type |  Value 
---------------+---------+--------------------- 
sequence_name | name | episode_id_seq 
last_value | bigint | 1 
start_value | bigint | 1 
increment_by | bigint | 1 
max_value  | bigint | 9223372036854775807 
min_value  | bigint | 1 
cache_value | bigint | 1 
log_cnt  | bigint | 32 
is_cycled  | boolean | f 
is_called  | boolean | t 
Owned by: public.episode.id 

Answer 1

您可以使用ALTER SEQUENCE

1. ALTER SEQUENCE episode_id_seq RENAME TO sequence_id_seq;

3. ALTER SEQUENCE episode_id_seq OWNED BY sequence.id;
