Обсуждение: pgsql: Make RecordTransactionCommit() respect wal_level.

Log Message:
-----------
Make RecordTransactionCommit() respect wal_level.

Since the only purpose of WAL-loggin SharedInvalidationMessages is to support
Hot Standby operation, they needn't be included when wal_level < hot_standby.

Back-patch to 9.0.
