無法使用“ pg” gem連接到postgres？

Question

我在嘗試測試與postgres的連接時使用以下代碼：

require 'pg'

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

我得到了錯誤：

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

但是我有一個具有相同憑據的python腳本，看起來很不錯：

import psycopg2

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

給定python腳本，我想知道我是否輸入了錯誤的憑證？

您的密碼（ puppetbdb ）中有一個錯字：

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