On Windows, if logged in as an Administrator, 'make check' fails with our standard error, saying:
<quote> Execution of PostgreSQL by a user with administrative permissions is not permitted. The server must be started under an unprivileged user ID to prevent possible system security compromises. See the documentation for more information on how to properly start the server. </quote>
But, for some time now, a Windows' Administrator *can* run a postgres without having to create a normal user; he just has to use pg_ctl to do so. Thanks to code written by Magnus, pg_ctl gives up it's administrative privilges before starting the postmaster, and hence the postmaster runs without critical privileges.
So I thought that 'make check' could also make use of that functionality, and hence this patch.
Is this new pg_ctl behavior mentioned anywhere in the docs?
