无法使用 'pg' gem 连接到 postgres？

Question

我在尝试测试与 postgres 的连接时使用以下代码：

require 'pg'

conn = PGconn.connect("localhost", 5432, '', '', "puppetdb", "puppetdb", "puppetbdb")
res  = conn.exec('select tablename, tableowner from pg_tables')

我找回了错误：

test.rb:3:in initialize': FATAL: password authentication failed for user "puppetdb" (PG::ConnectionBad) from test.rb:3:innew' from test.rb:3:in `'

但我有一个 python 脚本，它具有相同的凭据，似乎运行良好：

import psycopg2

try:
    conn = psycopg2.connect("dbname='puppetdb' user='puppetdb' host='localhost' port='5432' password='puppetdb'")

鉴于 python 脚本，我想知道我是否输入了错误的凭据？

您的密码有误 (puppetbdb):

conn = PGconn.connect("localhost", 5432, '', '', "puppetdb", "puppetdb", "puppetdb")
