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 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.)
