Nice cleanup overall.

{
- /* Okay to use page. Initialize and return it. */
- _bt_pageinit(page, BufferGetPageSize(buf));
- return buf;

There is only one caller of _bt_log_reuse_page(), so assigning a
boolean rather than the heap relation is a bit strange to me. I think
that calling RelationIsAccessibleInLogicalDecoding() within
_bt_log_reuse_page() where xlrec_reuse is filled with its data is much
more natural, like HEAD. One argument in favor of HEAD is that it is
not possible to pass down a wrong value for isCatalogRel, but your
patch would make that possible.
