pgsql-sdbc: use libpq's custom free()...

... for stuff allocated by libpq

Their documentation says this is important on Microsoft Windows:

It is particularly important that this function, rather than free(),
be used on Microsoft Windows. This is because allocating memory in a
DLL and releasing it in the application works only if
multithreaded/single-threaded, release/debug, and static/dynamic
flags are the same for the DLL and the application.

Also use const unique_ptr since we don't need the value to survive the
scope in any way.
