查找 Postgres 的副本标识 table

Question

有没有办法查看 Postgres table 具有哪种副本身份，无论是使用 pgAdmin 还是通过查询？

Answer 1

您可以查询pg_class系统目录：

SELECT CASE relreplident
          WHEN 'd' THEN 'default'
          WHEN 'n' THEN 'nothing'
          WHEN 'f' THEN 'full'
          WHEN 'i' THEN 'index'
       END AS replica_identity
FROM pg_class
WHERE oid = 'mytablename'::regclass;
