LOAD
LOAD
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 36.10.1 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
