commit    9d974fa39d264df2033ea04bf740d39acd5a3943
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Tue Oct 16 17:56:58 2018 +0000
First released in: 12.0, 9.3.25, 9.4.20, 9.5.15, 9.6.11, 10.6, 11.1

    Avoid rare race condition in privileges.sql regression test.
    
    We created a temp table, then switched to a new session, leaving
    the old session to clean up its temp objects in background.  If that
    took long enough, the eventual attempt to drop the user that owns
    the temp table could fail, as exhibited today by sidewinder.
    Fix by dropping the temp table explicitly when we're done with it.
    
    It's been like this for quite some time, so back-patch to all
    supported branches.
