Thomas fixed several bugs in DSA, which will be in next release, postgres 10.8 and 11.3. However that doesn't explain the segfault you saw, and I don't see anything which looks relevant changed since in 10.5. If you still see that using the latest minor release (10.7), please try to capture a core file and send a backtrace with a new thread on pgsql-hackers. Thanks, Justin
