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 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.
