title: PANIC: could not open control file "global/pg_control": Permission denied
body: <p>I have to postgres 11 and 14 installed on my computer. When I run pg_upgrade to migrate the databases I get the following error:</p>
  <blockquote>
  <p>PANIC: could not open control file &quot;global/pg_control&quot;: Permission denied</p>
  </blockquote>
  <p>However if I give the Window User full control of data directories of 11 and 14, then the upgrade works. Can someone help me what am I doing wrong since I am running pgupgrade from powershell started as admin.</p>
