PostgreSQLを使用していて、database.ymlで指定されたものと一致するパスワードを持つユーザーがいます
postgres=# select * from pg_user
;
usename | usesysid | usecreatedb | usesuper | usecatupd | userepl | passwd | valuntil | useconfig
------------+----------+-------------+----------+-----------+---------+----------+----------+-----------
goodsounds | 16386 | t | t | t | t | ******** | |
postgres | 10 | t | t | t | t | ******** | |
(2 rows)
しかし、コマンドを実行してデータベースを作成しようとすると
rails db:create
エラーが発生します

これが私のpg_hba.confです：
# Database administrative login by Unix domain socket
local all postgres peer
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all peer
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres peer
#host replication postgres 127.0.0.1/32 trust
#host replication postgres ::1/128 trust
以前は上記の「信頼」はmd5でしたが、それが役立つかどうかを確認するために変更しました。
これが私のdatabase.ymlです：
