Fix a nasty bug that was zeroing out clog and subtrans pages, thus causing
various sorts of data corruptions.
The bug dates back to the XC days, but probably became prominent in XL because
of certain recent changes. In XC/XL, a node may not see all the XIDs and hence
clog/subtrans log must be extended whenever a new XID crosses the previously
seen page boundary. We do this by comparing the pageno where the new XID maps
with the latest_page_no as stored in the shared SLRU data structure. But to
handle XID wrap-arounds, we added a check for difference in number of pages 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
aborted, resulting in removal of perfectly valid tuples.
This patch fixes the mess by just relying on built-in routines for checking
XID wrap-arounds.
I also found another issue while working on this. We must not only zero the
page at hand, but also all intermediate pages because we won't this opportunity
later if an intermediate XID is seen.
In our test setup, this seems to help some of the recent reports of data
corruption, including "missing attributes" errors.
