Обсуждение: pgsql: Factor error generation out of ExecPartitionCheck.

Factor error generation out of ExecPartitionCheck.

At present, we always raise an ERROR if the partition constraint
is violated, but a pending patch for UPDATE tuple routing will
consider instead moving the tuple to the correct partition.
Refactor to make that simpler.
