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 particular, one can rely
       on a search path and automatic addition of the system's standard shared library file name extension. See Section 35.9, "C-Language
       Functions", 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.
