NAME

LOAD - 裝載或重載一個共享庫文件

SYNOPSIS

LOAD 'filename'

DESCRIPTION 描述

 這個命令裝載一個共享庫文件到PostgreSQL服務器的地址空間。 一旦一個文件被裝載，如果該文件前面曾經裝載過，那么服務器首先會卸載它。 這條命令主要用于在一個共享庫件修改后卸載和重載它。 要利用這個共享庫件，我們必須用 CREATE FUNCTION [create_function(7)] 命令聲明函數。

 文件名是和 CREATE FUNCTION [create_function(7)] 里描寫的共享庫的名字相同方法聲明的； 特別要注意等是我們可以依賴搜索路徑和自動附加系統標準共享庫擴展名的特點。 參閱 Section 31.3 ``User-Defined Functions'' 獲取更多細節。

NAME

LOAD - load or reload a shared library file

SYNOPSIS

LOAD 'filename'

DESCRIPTION

This command loads a shared library file into the PostgreSQL server's address space. If the file had been loaded previously, it is first unloaded. This command is primarily useful to unload and reload a shared library file that has been changed since the server first loaded it. To make use of the shared library, function(s) in it need to be declared using the CREATE FUNCTION [create_function(7)] command.

The file name is specified in the same way as for shared library names in CREATE FUNCTION [create_function(7)]; in particular, one may rely on a search path and automatic addition of the system's standard shared library file name extension. See the section called ``User-Defined Functions'' in the documentation for more information on this topic.  

COMPATIBILITY
