LOAD
LOAD 'filename'
Description
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 (string)
dynamic_library_path configuration parameter
dynamic loading](braised:ref/runtime-config-client#dynamic-library-path-string-dynamic-library-path-configuration-parameter-dynamic-loading)). 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 [Dynamic Loading](braised:ref/xfunc-c#dynamic-loading) 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.)
