我有一个 Amazon RDS Postgres 数据库，我创建了一个“复制器”用户并授予它“复制”权限。
db=> create role replicator login password 'something';
CREATE ROLE
db=> alter role replicator replication;
ALTER ROLE
db=>
但是，当我尝试pg_basebackup从目标主机运行以创建副本时，出现 pg_hba.conf 错误：
# pg_basebackup -D /data/from-master -U replicator -h db-master.example.com -v
pg_basebackup: could not connect to server: FATAL: no pg_hba.conf entry for replication connection from host "10.1.20.19", user "replicator", SSL on
FATAL: no pg_hba.conf entry for replication connection from host "10.1.20.19", user "replicator", SSL off
问题是，这是 RDS，我根本无法访问 pg_hba.conf。有任何想法吗？
