Обсуждение: pgsql: Fix the database-wide version of CLUSTER to silently skip temp

Log Message:
-----------
Fix the database-wide version of CLUSTER to silently skip temp tables of
remote sessions, instead of erroring out in the middle of the operation.

This is a backpatch of a previous fix applied to CLUSTER to HEAD and 8.2, all
the way back that it is relevant to.
