## Problem - #7451 INIT_FORKNUM blocks must be stored on shard 0 to enable including them in basebackup. This issue can be missed in simple tests because creating an unlogged table isn't sufficient -- to repro I had to create an _index_ on an unlogged table (then restart the endpoint). Closes: #7451 ## Summary of changes - Add a reproducer for the issue. - Tweak the condition for `key_is_shard0` to include anything that isn't a normal relation block _and_ any normal relation block whose forknum is INIT_FORKNUM. - To enable existing databases to recover from the issue, add a special case that omits relations if they were stored on the wrong INITFORK. This enables postgres to start and the user to drop the table and recreate it.
