Subject: [PATCH v37 2/3] Mark role as GUC_REPORT

Mark the role GUC as GUC_REPORT to ensure changes are communicated
to the client. This is necessary for accurately reflecting the session's
is_superuser status, as either the role or session authorization can influence it.

This will support upcoming enhancements to the \conninfo+
meta-command, which will include more detailed session
information, such as role and authorization.
