Table 没有 DELETE 或 UPDATE 操作需要 VACUUM？
Table with no DELETE or UPDATE operations needs VACUUM?
文档说：
VACUUM reclaims storage occupied by dead tuples. In normal PostgreSQL operation, tuples that are deleted or obsoleted by an update are not physically removed from their table; they remain present until a VACUUM is done.
我每天有 table 约 50 000 INSERT 和更多 SELECT 操作，但没有 DELETE 或 UPDATE 操作全部就此 table。
问题是：我是否需要定期 VACUUM 来实现此 table？或者在这种特殊情况下，这根本没有意义？
这样的 table 需要清理的唯一原因是 冻结 元组（将它们标记为永久有效），这样它们就不会在交易柜台环绕。
每个元组只需要发生一次。
