无法登录，显示错误消息如下：
Error：login disallowed for security reasons.
解决方法：
修改conf/config.inc.php文件中的extra_login_security变量，由默认的false改为true
$conf[‘extra_login_security‘] = false;
由于phppgadmin设置了很多默认值，如果登录信息如端口号或者host不同，可直接修改config.ini.php文件。
登录成功后无法显示数据库，提示版本不支持
error：version of postgresql not supported. please upgrade to version or later.
解决方法如下：添加 case ‘10.‘: 到代码中即可
I change the file:*/usr/share/phppgadmin/classes/database/Connection.php*// Detect version and choose appropriate database driverswitch (substr($version,0,3)) { ???????case ‘10.‘: // add this line to fix partialy the problem* ???????case ‘9.2‘: return ‘Postgres‘; break; ???????case ‘9.1‘: return ‘Postgres91‘; break; ???????case ‘9.0‘: return ‘Postgres90‘; break; ???????case ‘8.4‘: return ‘Postgres84‘; break; ???????case ‘8.3‘: return ‘Postgres83‘; break; ???????case ‘8.2‘: return ‘Postgres82‘; break; ???????case ‘8.1‘: return ‘Postgres81‘; break; ???????case ‘8.0‘: ???????case ‘7.5‘: return ‘Postgres80‘; break; ???????case ‘7.4‘: return ‘Postgres74‘; break;}使用phppgadmin 遇到的小问题
