Fix #7204. https://github.com/neondatabase/postgres/pull/400 https://github.com/neondatabase/postgres/pull/401 https://github.com/neondatabase/postgres/pull/402 These commits never go into prod. Detailed investigation will be posted in another issue. Reverting the commits so that things can keep running in prod. This pull request adds the test to start two replicas. It fails on the current main https://github.com/neondatabase/neon/pull/7210 but passes in this pull request. --------- Signed-off-by: Alex Chi Z <chi@neon.tech>
