是的，您可以同时运行它。
您的主节点中应具有以下配置：

listen_addresses = '*'
port = 5432
wal_level = hot_standby
max_wal_senders = 16
wal_keep_segments = 32
synchronous_commit = on
synchronous_standby_names = 'pgsql_0_node_0'

重新启动节点以接受更改：

$ systemctl restart postgresql-14

创建复制角色：

$ CREATE ROLE replication_user WITH LOGIN PASSWORD 'PASSWORD' REPLICATION;

并在备用节点中进行配置：
两者：

wal_level = hot_standby
hot_standby = on

同步：

standby_mode = 'on'
promote_trigger_file='/tmp/failover_5432.trigger'
recovery_target_timeline=latest
primary_conninfo='application_name=pgsql_0_node_0 host=PRIMARY_NODE port=5432 user=replication_user password=PASSWORD'

用正确的值替换PRIMARY_NODE、用户和口令。

异步：

promote_trigger_file='/tmp/failover_5432.trigger'
recovery_target_timeline=latest
primary_conninfo='application_name=pgsql_0_node_1 host=PRIMARY_NODE port=5432 user=replication_user password=PASSWORD'

用正确的值替换PRIMARY_NODE、用户和口令。

重新启动节点以接受更改：

$ systemctl restart postgresql-14

然后，您可以在主节点中运行此命令以查看复制节点：

$ SELECT pid,usename,application_name,state,sync_state FROM pg_stat_replication;

  pid  |     usename      | application_name |   state   | sync_state
-------+------------------+------------------+-----------+------------
 10951 | replication_user | pgsql_0_node_1   | streaming | async
 10952 | replication_user | pgsql_0_node_0   | streaming | sync
