Fix cross-version upgrades with XMLSERIALIZE(NO INDENT)

michaelpq · michaelpq · commit 310907aaf010 · 2025-02-21T20:37:36.000+09:00
Dumps from versions older than v16 do not know about NO INDENT in a XMLSERIALIZE() clause. This commit adjusts AdjustUpgrade.pm so as NO INDENT is discarded in the contents of the new dump adjusted for comparison when the old version is v15 or older. This should be enough to make the cross-version upgrade tests pass. Per report from buildfarm member crake. Oversight in 984410b.
