LOAD - load a shared library file
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.)
LOAD is a PostgreSQL extension.
