LOAD SQL - Language Statements LOAD load or reload a shared library file LOAD LOAD 'filename' This command loads a shared library file into the PostgreSQL server's address space. If the file had been loaded previously, it is first unloaded. This command is primarily useful to unload and reload a shared library file that has been changed since the server first loaded it. To make use of the shared library, function(s) in it need to be declared using the command. The file name is specified in the same way as for shared library names in ; in particular, one can rely on a search path and automatic addition of the system's standard shared library file name extension. See for more information on this topic. $libdir/plugins 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.) LOAD is a PostgreSQL extension.
