$ make install
$ /sbin/ldconfig /usr/local/programs/postgresql/lib ## 刷新下共享动态库
$ cd /usr/local/programs/postgresql
$ bin/psql --version  ## 检查运行情况
## 开始对postgresql的配置
$ vi /etc/profile.d/postgresql.sh ## 增加环境变量,不推荐直接在/etc/profile中添加,系统更新升级时会需要merge
``` 
PATH=/usr/local/programs/postgresql:$PATH
export PATH
```
$ source /etc/profile ## 更新环境变量

## 增加用户和其他文件夹
$ adduser postgres
$ passwd postgres 
$ mkdir /usr/local/programs/postgresql/logs
$ mkdir /usr/local/programs/postgresql/data
$ chown postgres /usr/local/programs/postgresql/data
$ su - postgres

## 初始化数据库
$ ./bin/initdb -D ./data
$ ./bin/createdb test
$ ./bin/psql test
## 已有数据库，可导入data文件夹后尝试root访问，假如带密码，可能需要进一步研究下
$ ./bin/postgres -D ./data >./logs/start-log-1.log 2>&1 &
$ ./bin/psql --list  ##列出数据库
## ok，安装完成

## 自定义设置，权限控制等，可以跳过，等熟悉使用后再做
## 编辑数据库配置及权限文件：
$ vi /usr/local/programs/postgresql/data/postgresql.conf   ## 数据库配置文件
$ chown postgres postgresql.conf
$ chmod 644 postgresql.conf
$ vi /usr/local/programs/postgresql/data/pg_hba.conf   ## 权限文件
$ vi /usr/local/programs/postgresql/data/pg_ident.conf

## 设置开机自启动：
$ vi /etc/rc.d/rc.local    ## 添加如下内容
```
/usr/local/programs/postgresql/bin/postgresql start
```

## 查阅官方的bug，发现：
> id=66582: status : Closed. Fixed in master (PHP7)
> id=42718: status : Assigned
> id=42718: reference to id=49184, unsolved for many years
## 那就不关心了，直接装吧
$ make install
> You may want to add: /usr/local/programs/php/lib/php to your php.ini include_path

## 那就按它说的设置吧
$ cp php.ini-development /usr/local/programs/php/lib/php.ini
```
include_path = ".;/usr/local/programs/php/lib/php"

## 然后，编辑httpd的设置，确保其能正确解析php文件
```
...
LoadModule php5_module modules/libphp5.so
...
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .php5

...
<ifmodule dir_module>
    DirectoryIndex index.html index.php
</ifmodule>     
```

## 重启httpd，测试
$ cd /usr/local/programs/apache2
$ bin/httpd -h
$ bin/httpd -k stop
$ bin/httpd -f conf/httpd.conf
## 默认设置的www页面在./htdocs/下，那就先去里面建一个测试页面吧
$ vi htdocs/index.php
```
<?php phpinfo(); ?>
```
$ curl http://localhost/index.php |grep postgresql
#ok

解决方法

我刚刚发现一个选项，这是从视图中删除加入表，当我不会更改返回的列时，我可以这样做。但是，仍然有更多的意见需要改变。是不是有什么可以说，它应该推迟和检查与提交？

限制延期不适用于此问题。换句话说，即使SET CONSTRAINTS ALL DEFERRED也没有影响这个限制。具体来说，约束延迟不适用于打印错误的一致性检查：当尝试更改视图下面的列的类型时，不能更改视图或规则使用的列的类型。
