When I ran the long-running performance test, I encountered the following
panic error.
PANIC: could not find WAL buffer for 0/FF000000
0/FF000000 is the xlog file boundary, so the patch seems to handle
the xlog file boundary incorrectly. In the patch, current insertion lsn
is advanced by directly incrementing XLogRecPtr.xrecoff as follows.
But to handle the xlog file boundary correctly, we should use
XLByteAdvance() for that, instead?
