Обсуждение: [HACKERS] Running some tests with different segment sizes
Hi, I'm working on merging the customizable segment size patch [1]. I'd like to run some of the regression tests using it, to guarantee non-standard settings have test coverage. The reason I'd like to adapt an existing test, rather than add a new run of the standard regression tests, is to avoid bloating the regression time unnecessarily. I thought about starting with just changing pg_upgrade's rerun of the standard test. Then maybe change one or two tests in src/test/recovery/? Complaints, better ideas?

Maybe there's a way to set up a buildfarm animal or two that run all the tests with a different segsize? regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

Hm, that'd work too. We could make initdb look at getenv("PG_DEFAULT_SEGSIZE") or such? Otherwise it's probably not easy to have all tests respect that. I still would like to have at least one test that explicitly specifies a different size so people can see if they outright break something, but one would be enough if we had such an animal.
