Prevent instability in contrib/pageinspect's regression test. pageinspect has occasionally failed on slow buildfarm members, with symptoms indicating that the expected effects of VACUUM FREEZE didn't happen. This is presumably because a background transaction such as auto-analyze was holding back global xmin.
We can work around that by using a temp table in the test. Since commit a7212be8b, that will use an up-to-date cutoff xmin regardless of other processes. And pageinspect itself shouldn't really care whether the table is temp. Back-patch to v14. There would be no point in older branches without back-patching a7212be8b, which seems like more trouble than the problem is worth.
