Now that beta is out, I wanted to do some crash-recovery testing where I inject PANIC-inducing faults and see if it recovers correctly. A long-lived Perl process keeps track of what it should find after the crash, and verifies that it finds it. You will probably be familiar with the general theme from examples like the threads below. Would anyone like to nominate some areas to focus on? I think the pluggable storage refactoring work will be get inherently tested, so I'm not planning designing test specifically for that (unless there is a non-core plugin I should test with). Making the ctid be tie-breakers in btree index is also tested inherently (plus I think Peter tested that pretty thoroughly himself with similar methods). I've already tested declarative partitioning where the tuples do a lot of migrating, and tested prepared transactions. Any other suggestions for changes that might be risky and should be specifically targeted for testing?
