For example, if page lsn in storage is 0x9 and start to replay from 0x1.
If 0x1 is full-page xlog record, then we can ignore to replay xlog between

Is there any correct issue if the page exists in the buffer pool and ignore to
replay for full-page or i

During crash recovery, we compare most of the lsn of xlog record with page lsn

The exceptions are full-page and init-page xlog records.
It's restored if the xlog record includes a full-page image of the page.
