postgresql中一个序列对象通常用于为行或者表生成唯一的标识符。查看序列：psql 的 \d 命令输出一个数据库对象，包括 Sequence，表，视图和索引。你还可以使用 \ds 命令只查看当前数据库的所有序列。例如：pigdb-# \ds List of relations Schema | Name | Type | Owner--------+-----------------------+----------+-------- public | author_ids | sequence | ichexw public | shipments_ship_id_seq | sequence | ichexw(2 rows)
select relname from pg_class where relowner=(select usesysid from pg_user where usename='yourusername') and relkind='s'
select relname from pg_class where relowner=(select usesysid from pg_user where usename='yourusername') and relkind='s'
