.SH "NAME"
LOAD \- load a shared library file
.SH "SYNOPSIS"
.sp
.nf
LOAD \*(Aq\fIfilename\fR\*(Aq
.fi
.SH "DESCRIPTION"
.PP
This command loads a shared library file into the
PostgreSQL
server\*(Aqs 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
\fBLOAD\fR
is usually only needed to load a library that modifies the server\*(Aqs behavior through
\(lqhooks\(rq
rather than providing a set of functions\&.
.PP
The library file name is typically given as just a bare file name, which is sought in the server\*(Aqs library search path (set by
dynamic_library_path)\&. Alternatively it can be given as a full path name\&. In either case the platform\*(Aqs standard shared library file name extension may be omitted\&. See
Section\ \&38.10.1
for more information on this topic\&.
.PP
Non\-superusers can only apply
\fBLOAD\fR
to library files located in
$libdir/plugins/
\(em the specified
\fIfilename\fR
must begin with exactly that string\&. (It is the database administrator\*(Aqs responsibility to ensure that only
\(lqsafe\(rq
libraries are installed there\&.)
.SH "COMPATIBILITY"
.PP
\fBLOAD\fR
is a
PostgreSQL
extension\&.
