wp-cli db export

wp db export - | gzip > /tmp/wp-`date +\%Y\%m\%d`.sql.gz
mysqldump: Error: 'Access denied; you need (at least one of) the PROCESS privilege(s) for this operation' when trying to dump tablespaces

wp-cli 2.4.0 は --include-tablespaces オプションがなく include-tablespaces 相当で動作

wp-cli 2.10.0 に更新してエラー解消
