Description:

Hello,

from the documentation i read that LOAD loads a shared library.

While creating extensions in C it is very cumbersome to disconnect, restart,
connect everytime I recompile my C stuff.

A reload option wouldn't help also because on Windows I cannot overwrite the
DLL while it is opened in Postgres, so I need an UNLOAD command.
