PHP无法连接到PGSQL

Question

我无法让PHP连接到PGSQL。我正在运行小牛10.9.4。以下是我遵循的步骤：

1. 弄清楚PHP w / mac的默认生活位置（which php）
2. rmdir该目录
3. brew install php54
4. php -v显示新的php 5.4
5. php -m显示没有pdo_pgsql模块
6. brew install php54-pdo-pgsql
7. php -m显示pdo_pgsql模块
8. php -i显示以下信息

PDO support => enabled
PDO drivers => mysql, odbc, sqlite, pgsql

pdo_mysql

PDO Driver for MySQL => enabled
Client API version => mysqlnd 5.0.10 - 20111026 - $Id: c85105d7c6f7d70d609bb4c000257868a40840ab $

Directive => Local Value => Master Value
pdo_mysql.default_socket => /tmp/mysql.sock => /tmp/mysql.sock

PDO_ODBC

PDO Driver for ODBC (unixODBC) => enabled
ODBC Connection Pooling => Enabled, strict matching

pdo_pgsql

PDO Driver for PostgreSQL => enabled
PostgreSQL(libpq) Version => 9.4.4
Module version => 1.0.2
Revision =>  $Id: 8e4cc97fb53f418d98b489c3e9d722e48446e676 $ 

1. 打开/usr/local/etc/php/5.4/php.ini并添加extension=pgsql.so，然后保存
2. sudo apachectl restart
3. 打开phpinfo（）页面
4. PDO驱动程序部分仅显示mysql, sqlite
5. Loaded Configuration File部分显示了php.ini与pgsql扩展名相同的文件

每当我在控制台中运行php命令时，我都会看到

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/Cellar/php54/5.4.43_2/lib/php/extensions/no-debug-non-zts-20100525/pgsql.so' - dlopen(/usr/local/Cellar/php54/5.4.43_2/lib/php/extensions/no-debug-non-zts-20100525/pgsql.so, 9): image not found in Unknown on line 0
