Remove useless and rather expensive stanza in matview regression test.
This removes a test case added by commitb69ec7c, which was intendedto exercise a corner case involving the rule used at that time thatmaterialized views were unpopulated iff they had physical size zero.We got rid of that rule very shortly later, in commit1d6c72a, butkept the test case. However, because the case now asks what VACUUMwill do to a zero-sized physical file, it would be pretty surprisingif the answer were ever anything but "nothing" ... and if things wereindeed that broken, surely we'd find it out from other tests. Sincethe test involves a table that's fairly large by regression-teststandards (100K rows), it's quite slow to run. Dropping it shouldsave some buildfarm cycles, so let's do that.Discussion:https://postgr.es/m/32386.1493831320@sss.pgh.pa.us
