LOAD
Description
This command loads a shared library file into thePostgreSQL 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 explicitLOAD 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 inCREATE FUNCTION; in particular, one can rely on a search path and automatic addition of the system's standard shared library file name extension. SeeSection 35.9 for more information on this topic.
Non-superusers can only applyLOAD to library files located in$libdir/plugins/ — the specifiedfilename must begin with exactly that string. (It is the database administrator's responsibility to ensure that only"safe" libraries are installed there.)
