with the latest_page_no as stored in the shared SLRU data structure. But to

be less than CLOG_WRAP_CHECK_DELTA, which was incorrectly defined as
(2^30 / CLOG_XACTS_PER_PAGE). Note that "^" is a logical XOR operator in C and
hence this was returned a very small number of 28, thus causing incorrect
zeroing of pages if ExtendCLOG is called with an XID which is older than what
28 clog pages can hold. All such transactions would suddenly be marked as
