Michael Paquier	c731f9187b	Replace magic constants for seek() calls in perl scripts ... A couple of tests have been using 0 as magic constant while SEEK_SET can be used instead. This makes the code easier to understand, and more consistent with the changes done in 3c5b068. Per discussion with Andrew Dunstan.

Alvaro Herrera	8deb6b38dc	Reinstate HEAP_XMAX_LOCK_ONLY|HEAP_KEYS_UPDATED as allowed ... Commit 866e24d47d added an assert that HEAP_XMAX_LOCK_ONLY and HEAP_KEYS_UPDATED cannot appear together, on the faulty assumption that the latter necessarily referred to an update and not a tuple lock; but that's wrong, because SELECT FOR UPDATE can use precisely that combination, as evidenced by the amcheck test case added here. Remove the Assert(), and also patch amcheck's verify_heapam.c to not complain if the combination is found. Also, out of overabundance of caution, update (across all branches) README.tuplock to be more explicit about this.

Tom Lane	c2dc1a7976	Disable vacuum page skipping in selected test cases. ... By default VACUUM will skip pages that it can't immediately get exclusive access to, which means that even activities as harmless and unpredictable as checkpoint buffer writes might prevent a page from being processed. Ordinarily this is no big deal, but we have a small number of test cases that examine the results of VACUUM's processing and therefore will fail if the page of interest is skipped. This seems to be the explanation for some rare buildfarm failures. To fix, add the DISABLE_PAGE_SKIPPING option to the VACUUM commands in tests where this could be an issue. In passing, remove a duplicated query in pageinspect/sql/page.sql. Back-patch as necessary (some of these cases are as old as v10).

Tom Lane	321633e17b	Fix more portability issues in new amcheck code. ... verify_heapam() wasn't being careful to sanity-check tuple line pointers before using them, resulting in SIGBUS on alignment-picky architectures. Fix that, add some more test coverage. Mark Dilger, some tweaking by me Discussion: https://postgr.es/m/30B8E99A-2D9C-48D4-A55C-741C9D5F1563@enterprisedb.com	5 years ago
Tom Lane	860593ec3b	Fix portability issues in new amcheck test. ... The tests added by commit 866e24d47 failed on big-endian machines due to lack of attention to endianness considerations. Fix that. While here, improve a few small cosmetic things, such as running it through perltidy. Mark Dilger Discussion: https://postgr.es/m/30B8E99A-2D9C-48D4-A55C-741C9D5F1563@enterprisedb.com	5 years ago
