NAME

       LOAD - load a shared library file

SYNOPSIS

       LOAD 'filename'

DESCRIPTION

           Note

           The following description applies both to Postgres-XC and PostgreSQL if not described explicitly.

       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 Section 36.9, “C-Language Functions”, 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.)

           Note

           The following description applies only to Postgres-XC

       Please note that LOAD command loads library only locally. You should load library manually in each
       Datanode and Coordinator (you can use psql directly to Datanodes for this puupose), or edit
       postgresql.conf for all the Datanodes and Coordinators.
