Hi, I quickly looked at this patch and I think there's major missing pieces around buffer management and wal logging.
a) Currently buffers that are in memory marked as permanent/non-permanent aren't forced out to disk/pruned from cache, not even when they're dirty. b) When converting from a unlogged to a logged table the relation needs to be fsynced. c) Currently a unlogged table changed into a logged one will be corrupted on a standby because its contents won't ever be WAL logged.
