Speed up "brin" regression test a little bit.
In the large DO block, collect row TIDs into array variables instead of creating and dropping a pile of temporary tables. In a normal build, this reduces the brin test script's runtime from about 1.1 sec to 0.4 sec on my workstation. That's not all that exciting perhaps, but in a CLOBBER_CACHE_ALWAYS test build, the runtime drops from 20 min to 17 min, which is a little more useful. In combination with some other changes I plan to propose, this will help provide a noticeable reduction in cycle time for CLOBBER_CACHE_ALWAYS buildfarm critters.
