NAME
       LOAD - load 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 has been loaded already,
       the command does nothing. Shared library files that contain C functions are automatically loaded whenever  one  of  their
       functions  is  called.   Therefore,  an explicit LOAD is usually only needed to load a library that modifies the server's
       behavior through ``hooks'' rather than providing a set of functions.

       The file name is specified in the same way as for shared library names in CREATE FUNCTION [create_function(7)];  in  par-
       ticular,  one  can  rely on a search path and automatic addition of the system's standard shared library file name exten-
       sion. See in the documentation for more information on this topic.


       Non-superusers can only apply LOAD to library files located in $libdir/plugins/ -- the specified filename must begin with
       exactly  that  string.  (It  is  the  database  administrator's responsibility to ensure that only ``safe'' libraries are
       installed there.)

COMPATIBILITY
       LOAD is a PostgreSQL extension.
