## 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 library file name is typically given as just a bare file name, which is sought in the
       server's library search path (set by dynamic_library_path). Alternatively it can be given as
       a full path name. In either case the platform's standard shared library file name extension
       may be omitted. See Section 38.10.1 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.
