Looking at your 0001 patch, which adds tests for some of the information_schema views, I think it's a bad idea to put them in whatever other regression .sql files; they would be subject to concurrent changes depending on what other tests are being executed in the same parallel test. I suggest to put them all in a separate .sql file, and schedule that to run in the last concurrent group, together with the tablespace test. This way, it would capture all the objects left over by other test files.
