WAL-log the creation of the init fork of unlogged indexes.
We create a file, so we better WAL-log it. In practice, all thebuilt-in index AMs and all extensions that I'm aware of write ametapage to the init fork, which is WAL-logged, and replay of themetapage implicitly creates the fork too. But if ambuildempty() didn'twrite any page, we would miss it.This can be seen with dummy_index_am. Set up replication, create a'dummy_index_am' index on an unlogged table, and look at the filescreated in the replica: the init fork is not created on thereplica. Dummy_index_am doesn't do anything with the relation files,however, so it doesn't lead to any user-visible errors.Backpatch to all supported versions.Reviewed-by: Robert HaasDiscussion:https://www.postgresql.org/message-id/6e5bbc08-cdfc-b2b3-9e23-1a914b9850a9%40iki.fi1 parent34f6c60 commitc50b869
