执行 online ddl 时需要修改目标表的 append_mode 值，如下代码所示拼装 SQL 语句时没有使用双引号括起来，导致一些特殊名称的表对应的 alter 语句执行失败
bool OnlineDDLInstanceInit(Relation* relation, LOCKMODE lockmode, OnlineDDLType onlineDDLType, Oid partitionOid) { appendStringInfo(query, "ALTER TABLE %s.%s SET (append_mode = online_ddl)", get_namespace_name((*relation)->rd_rel->relnamespace), (*relation)->rd_rel->relname.data); }操作系统和硬件信息
