ansible模块postgresql_schema不支持从数据库中对单个模式进行备份和还原。

Question

我曾尝试从Postgres数据库中备份和还原单个模式，但得到以下错误，使用下面的yml文件我也使用了postgresql_db模块，但得到错误。

fatal: [192.168.1.18]: FAILED! => {"changed": false, "msg": "Unsupported parameters for (postgresql_schema) module: target Supported parameters include: ca_cert, cascade_drop, database, login_host, login_password, login_unix_socket, login_user, owner, port, schema, session_role, ssl_mode, state"}

---

- hosts: dbserver
  become: true
  gather_facts: yes

  vars:
    dbname: dbname
    dbuser: dbuser
    password: dbpassword

  tasks:
  - name: Schema backup
    postgresql_schema:
      name: dbname
      schema: schema1
      state: dump
      target: /tmp/schema.sql.gz
      login_user: "{{ dbuser }}"
      login_password: "{{ password }}"

Answer 1

我已经使用postgresql_db模块进行单模式备份，工作正常，public是模式名。

- name: Dump a single schema for an existing database
  postgresql_db:
    name: acme
    state: dump
    target: /tmp/acme.sql
    target_opts: "-n public"
